Determining the ripening of a fruit is critical to a farmer, since the fresher the fruit, the better it will be priced and sold. This is also critical to the economy since the ninth (9th) most exported good in the Philippines is fruits. The researchers made use of Convolutional Neural Networks through imageprocessing to determine the fruit maturity of Banana (Cavendish), Mango (Carabao), Calamansi/Calamondin, will classify said fruits into three categories for the fruit maturity: pre-matured, matured, over-matured. Of the sixty fruits used, twenty pieces of which will be used to gather data, starting from their very unripe/pre-matured stage up-to the over-matured stage. This will approximately take one (1) to two (2) weeks if stored in room temperature. The total data gathered would be 3681 pieces for Calamansi (Philippine lime);3270 pieces for Banana (Cavendish);and 5706 pieces for Mango (Carabao). The model is written in Spyder in Anaconda Navigator, which will be applying Tensorflow-GPU and Keras. These will also be coupled with CUDA and CUDDN to process the data and determine the results. Two total experiments will be executed - one for the Red-Green-Blue (RGB) dataset, and one for the greyscale dataset.

In the last few years, generative adversarial networks (GAN) have shown tremendous potential for a number of applications in computervision and related fields. With the current pace of progress, it is a sure bet they will soon be able to generate high-quality images and videos, virtually indistinguishable from real ones. Unfortunately, realistic GAN-generated images pose serious threats to security, to begin with a possible flood of fake multimedia, and multimedia forensic countermeasures are in urgent need. In this work, we show that each GAN leaves its specific fingerprint in the images it generates, just like real-world cameras mark acquired images with traces of their photo-response non-uniformity pattern. Source identification experiments with several popular GANs show such fingerprints to represent a precious asset for forensic analyses.

Recent advances in vehicular technology and sensing devices has led to the proliferation of different approaches for road surface condition monitoring and road anomaly detection. These approaches can be categorized into vision-based and accelerometer-based techniques. These techniques are designed to enable vehicles detect road anomalies and notify drivers of such, thereby reducing the rate of anomalous induced accidents. Also, these approaches can be incorporated into autonomous vehicles towards navigating through road terrains with anomalies such as potholes, speed bumps and rutting. The vision-based techniques have received wide acceptance among academia and industry players alike because of their inherent ability to detect road anomalies in real-time and notify drivers easily. In this regard, this paper presents a mini-survey of various state-of-the-art vision-based techniques proposed in the literature for road surface condition monitoring and anomaly detection. The merits and drawbacks of these techniques are highlighted. Furthermore, open research issues are presented. Our effort forms part of a larger goal aimed at developing robust visionprocessing approaches for road anomaly detection, as well as benefiting researchers involved in similar pursuits.
Based on machine vision, this paper uses Matlab to perform imageprocessing andimage recognition on the image signals of mechanical parts collected, and transmits the control signals wirelessly through Zigbee to real...

In the human-computer interaction (HCI) field, facial feature analysis and extraction are the most decisive stages which can lead to a robust and efficient classification system like facial expression recognition, emotion classification. In this paper, an approach to the problem of automatic facial feature extraction from different videos are presented using several image algebraic operations. These operations deal with pixel intensity values individually through some mathematical theory involved in image analysis and transformations. In this paper, 11 operations (point subtraction, point addition, point multiplication, point division, edge detecting, average neighborhood filtering, image stretching, log operation, exponential operation, inverse filtering, andimage thresholding) are implemented and tested on the images (video frames) extracted from three different self-recorded videos named as video1, video2, video3. The videos are in .avi, .mp4 and .wmv format respectively. The work is tested on two types of data: grayscale and RGB (Red, Green, Blue). To assess the efficiency of each operation, three factors are considered: processing time, frames per second (FPS) and sharpness of edges of feature points based on image gradients. The implementation has been done in MATLAB R2017a.

Economy of Bangladesh mostly depended on agriculture. As a small country, our population is over the limit. We are also a developing country also. For national GDP growth must be to increase the production. Every year a huge amount of agricultural production losses for the crop disease. As we know most of the farmers in our country are illiterate, have no proper knowledge about the disease, that's why they cannot manually detect the disease. I think if you properly detect the disease at the early stage we can solve the issue. We develop a model that can classify leaf disease. We focus on 5 major production crops in Bangladesh. Using computervision technique our farmer will get the benefit. We use convolutional neural networks for classifying images. An algorithm cannot properly capture the features of existing data that's why we use a pre-trained feature extraction method that is MobileNetv2. MobileNetv2 is very useful for mobile devices. The research contains the proportions of validation accuracy of 90.38%. This approach resulted in the agriculture sector that will help a farmer to classify disease from harvest. The main goal of our model is to minimize the damage of suffering plants that can help to the growth of production. By solving this issue themselves farmers can also reduce cost. Our goal is that they can cure their crop at the right time. To achieve this goal we tend to think that we should develop a way to detect the leaf disease. We collect several kinds of cucumber leaves. And then any leave can be tasted by our model. By using our model we try to reduce the leaf disease.

Postgraduate course teaching plays an important role in postgraduate education. With the development of “double first-class” construction and “new engineering disciplines”, it is imperative to reform the postgraduate course teaching, optimize the teaching system and improve the teaching effect. This paper takes the teaching of “imageprocessing andcomputervision” as an example to analyze and research the significance and role of teaching team in postgraduate courses, and discusses the advantages and characteristics of teaching team in the teaching process. We analyze the steps of how to teach the course, such as team building, course preparation, teaching, and assessment, and make a comparative analysis of the teaching effect. This paper summarizes that the teaching team is beneficial to improving the initiative and enthusiasm of students, improving the quality of teaching effectively. In addition, teaching team model can be popularized and applied to other courses.
