Abstract

This study focuses on the critical investigation of the propagation of the Aedes aegypti mosquito, a vector responsible for transmitting various diseases. The significance lies in understanding its spread due to its potential to disseminate illnesses. Employing laboratory-engineered traps called IoT-Ovitraps, the research aims to construct maps illustrating egg deposition within a community. To achieve this, images featuring the objects of interest, namely Aedes aegypti eggs, are captured using a Raspberry Pi equipped with a micro lens. The primary objective centers on the detection and enumeration of Aedes aegypti eggs within the confines of Cauayan City. To ascertain the most effective methodology for achieving accurate egg quantification, the study employs three distinct models. These models are subsequently compared for their precision in estimating egg quantities present in the ovitraps. Among the models assessed, the convolutional neural network (CNN) emerges as the superior option in terms of efficiency and dependability. Remarkably, the CNN model attains an impressive accuracy rate of 99.5% in accurately detecting and enumerating Aedes aegypti eggs. This outcome underscores the potential of advanced machine learning techniques in contributing to effective disease vector monitoring and control strategies, highlighting the promising role of neural networks in tackling the challenges posed by disease-carrying mosquitoes.

Introduction

An epidemic of dengue disease is spread by infected Aedes aegypti. When eggs were clumped with comparable things, disease carriers were difficult to locate. This illness has frequently endangered public health and even resulted in fatalities. To identify disease carriers at an early stage, several approaches and technologies, including computer vision and deep learning, had been explored. Aedes aegypti eggs can also be branded and mixed in with similar objects while still being recognized by a computer vision algorithm. Some studies (Bandong & Joelianto, 2019) (Santana et al., 2019) includes in their investigations are determined the size, shape, and color are the most important characteristics of eggs.

In the Philippines, the threat of dengue fever remains a significant public health concern due to the active transmission of the disease by the infected Aedes aegypti mosquito. The country has experienced recurrent outbreaks of dengue, posing substantial health risks and mortality rates. In response to the challenges posed by these disease carriers, innovative strategies and technological advancements have been explored to enhance early detection and control.

In order to effectively detect and count Aedes aegypti eggs in a particular location in Cauyan City, Isabela Province, Philippines. The researcher created a hardware which is called IoT-OviTrap that composed of Raspberry pi with micro lenses that is place over the black container with paddle or so called “DOST OL trap”. The hardware was being set with a time interval for capturing and automatically processed the capture images and then sends the result into the webserver.

The motivation of this study is to perform different computer vision models such as (OpenCV, Template Matching and Neural Network) to be package into the hardware and compare its results.

This study lies in its potential to address a pressing public health concern related to the spread of dengue disease through infected Aedes aegypti mosquitoes.

Dengue outbreaks have posed a significant threat to public health, leading to substantial morbidity and mortality. The challenge of detecting disease carriers becomes more complex when Aedes aegypti eggs are clustered among similar objects, making their identification and control arduous. Early detection and monitoring of these disease vectors are critical to implementing timely control measures.

By exploring innovative approaches such as computer vision and deep learning, this study aims to contribute to the development of effective tools and techniques for the detection and counting of Aedes aegypti eggs. The creation of the IoT-OviTrap hardware, which integrates Raspberry Pi with micro lenses, offers a practical solution for real-time image capture and analysis. The utilization of computer vision models like OpenCV, Template Matching, and Neural Network within the hardware holds the potential to enhance the accuracy and efficiency of egg detection.

Ultimately, the study's findings have the potential to inform and guide public health interventions, aiding in the early identification and management of Aedes aegypti populations. This research could contribute significantly to the field of disease vector control and monitoring, offering insights into innovative technological solutions that can be applied in other regions facing similar challenges.

The emergence and propagation of dengue disease carried by Aedes aegypti mosquitoes have engendered substantial health risks, necessitating effective control measures. However, the challenge of identifying these disease vectors is compounded when their eggs are clustered alongside similar objects. Traditional detection methods often fall short in accurately locating and quantifying these eggs. In response, this study seeks to address the problem of efficient and reliable Aedes aegypti egg detection within a specific location in Cauayan City, Isabela Province, Philippines.

Despite previous research efforts, there is a need for advanced technological solutions that combine hardware and computer vision techniques to enhance the accuracy and speed of egg detection. The development of the IoT-OviTrap, encompassing Raspberry Pi with micro lenses and integrated computer vision models, seeks to provide a holistic solution to this problem. The comparative analysis of computer vision models—OpenCV, Template Matching, and Neural Network—within the hardware framework further enhances the potential for accurate and early identification of Aedes aegypti eggs.

Potato Leaf Disease Detection Through Image Processing Techniques I InformativeBD

Rokon Uz Zaman, KU Ahmmad , Debasis Sarkar , MAA Mumin , and N Salahin, from the different institute of the Bangladesh. wrote a research article about, Potato Leaf Disease Detection Through Image Processing Techniques. Entitled, Potato leaf disease detection using image processing. This research paper published by the International Journal of Agronomy and Agricultural Research (IJAAR). an open access scholarly research journal on Agronomy. under the affiliation of the International Network For Natural Sciences | INNSpub. an open access multidisciplinary research journal publisher.

Abstract 

Agriculture is one of the most important pillars of Bangladesh’s economy. However, due to some factors such as plant diseases, pests, climate change, the yield of the farming industry decreases, and the productivity decreases as well. The detection of plant diseases is crucial to avert the losses in the productivity and in the yield. It is not obvious to monitor the plant diseases manually as the act of disease detection is very critical. It needs a huge effort, along with knowledge of plant diseases and extensive processing times. Therefore, image processing technology is used to detect the plant disease, this is done by capturing the input image that undergoes the process and is compared with the dataset. This dataset is composed of diverse diseases of potato leaves in the image format.  This study aims to build a web application to predict the diseases of potato plants that will help farmers to identify the diseases so that they can use appropriate fungicide to get more yields. The purpose of this study is to assist and provide efficient support to the potato farmers. In this study, we propose a system that will use the techniques of image process to both analyze and detect the plant diseases using machine learning Conventional Neural Networks (CNN) with Tensorflow framework 2. The results of the implementation show that the designed system could give a successful result by detecting and classifying the potato leaf diseases and healthy plant.

 Introduction

Agricultural industry is the backbone of our economy that contributes about 11.63% of GDP (BBS 2021). Potato is an important and leading crop in Bangladesh. Bangladesh is the seventh potato producing country in the world and ranks second after rice in terms of production and are the third most important food crop after rice and wheat in terms of human consumption in Bangladesh (FAOSTAT, 2020). According to the DAE statistics, about 9.61 million MT of potatoes have been produced in 2020 against the annual demand of about 6.82 million MT, bringing a surplus of 3.40 million MT despite some amounts is being exported (DAM, 2020). 

But in Bangladesh late blight is the most common and highly destructive, fungal disease in potato and annual potato yield losses due to late blight have been estimated at 25-57% (GEOPOTATO project report, 2016-2019). Plants are sensitive to diseases especially the plant leaves as symptoms of the disease appear first on the leaves. Due to the bad impacts of plant diseases on the both the economy and environment, the farmers should consider monitoring the crops in such a way that they may mitigate losses. It exists a way that is used by experts to monitor the crops which is the naked eye observation. This is a traditional method that has many constraints related to time consuming as the operation of monitoring is done manually, and it requires the presence of experts. However, lately, crop monitoring is being developed to be digital and semi-automatic, meaning that only from the symptoms that are shown on the leaf, the disease could be detected in an easier, quicker, cheaper way. Therefore, this digitalized method will be beneficial for the farmers as well since it will facilitate for them the detection of the diseases because most of the farmers do not have a sufficient background and knowledge about monitoring the crops and dealing with the variety of diseases that could affect them. There are many researcher reported, leaf dieses classification and detect is successfully possible by using image processing techniques of deep learning as well as machine learning. Different methods for machine learning and deep learning include the Support Vector Machines (SVM), Random. 

Forests (RF), K-nearest Neighbor (KNN), Artificial Neural Network (ANN), and Convolutional Neural Network (CNN), along with models such as AlexNet, GoogleNet, and Caffe are used to classify and detect to leaf dieses (Knaak et al., 2021). The report presented a machine-learning model including canny edge detection technique for edge feature extraction, grid color movement for extracting color features and local binary pattern (LBP) for texture analysis. Where the features were extracted combined to create a combined feature vector which was used for training the artificial neural network (ANN). The convolutional model is also capable of differentiating the plant leaves and recognizing rice plants and their diseases (Shrivastava et al., 2022). Potato leaf diseases were detected by using random forest classifiers where image pre-processing was done in two steps like image normalization and color space conversion where segmentation was done using thresholding HSV images in RGB color space and global feature descriptor (GFD), gray level cooccurrence matrix (GLCM), color histogram were used for extracting features. Finally, classification was done using random forest (RF) classifiers (Iqbal et al., 2020). The proposed system that we are suggesting in this paper could be used by the farmers to increase the yield with no need to consult experts. The core purpose of this proposed system is not aiming only at detecting the plant diseases using the image processing technology, but it aims also at directing the user farmer to use a mobile application in which he will upload the image and receive the type of disease infection along with a suggestion of needed pesticides. The digitalization of the agriculture field has known the intervention of the latest technologies namely the image processing. As a result, our system that is designed to be automated system is implemented using image processing technique using machine learning Convolutional Neural Networks (CNN) with Tensorflow Framework 2.

Abstract

Fish counting in aquaculture is an important task in fish population estimation. However, it is very challenging because of the diversity of backgrounds, uncertainty of fish motion, and obstruction between objects. To solve this problem, a model using Convolutional Neural Network (CNN) and Contrast Limited Adaptive Histogram Equalization (CLAHE) is proposed to provide an advanced and efficient counting method for aquaculture. The methodology involved image acquisition, CNN implementation, and evaluation. First, images were manually annotated from video frames. Then, a CNN was trained on the training dataset to detect the tilapia and determine its location. Lastly, the performance of the method was evaluated and compared with other assessment methods. The results show that the study gained 95%, 87%, and 91% for precision, recall, and F1-score, respectively. Further, the mean average precision at 0.5 resulted in 94.21%; thus, the study can detect and locate the fish in a tank and be integrated into a feeding management system.

Introduction

Accurate counting of organisms, such as Nile Tilapia (Oreochronis niloticus), is important for various applications, including fisheries management, environmental monitoring, and aquaculture operations (Li et al., 2020). In the Philippines, tilapia is the second most important cultured species, with approximately 281,111 MT of total production in 2021. In 2020, tilapia made up 20% of the aquaculture production in the country, with Central Luzon as the leading producer. Tilapia is an important commodity for food security and economic development (PCAARRD, n.d.).

The tilapia industry in the Philippines has made notable growth in production from 2002 to 2022, with an increase of 115.58%. This may be attributed to several programs done by the government, such as improving the strain of tilapia and improving the technology in production and culture to sustain industry growth (Bureau of Fisheries and Aquatic Resources, 2022).

However, despite the progress made in tilapia aquaculture, problems and challenges persist. Pollutionrelated problems like diseases and water quality management, sources of quality fingerlings, and market competition are among the key challenges faced by farmers (Bureau of Fisheries and Aquatic Resources, 2022). Addressing these challenges and enhancing the efficiency and sustainability of tilapia production is crucial for the industry's continued growth.

In this context, developing an automated methodology for accurate surface tilapia detection using a Convolutional Neural Network (CNN) brings an opportunity to improve tilapia farming practices. Leveraging the capabilities of CNN and Contrast Limited Adaptive Histogram Equalization (CLAHE) aims to develop an approach to determine whether Nile Tilapia are at the surface or submerged. The insights gained from this research can contribute to optimizing feeding strategies, improving management practices, and enhancing tilapia aquaculture's overall productivity.

The paper is presented as follows: Section 1 introduces the motivation for the research. Section 2 concentrated on the related works on image processing, CNN, and CLAHE. The methodology of the research is presented in Section 3. Section 4 presents the Tests and Results. Finally, Section 5 discussed the conclusion and future works.
