How does image enhancement help with object detection?5 answersImage enhancement plays a crucial role in improving object detection accuracy in visually degraded scenes. By integrating image enhancement with object detection, the detection network can be refined using additional enhancement branches, optimizing features to guide learning in object detection tasks. This approach ensures that the detection network is aware of both image quality and object detection, significantly enhancing performance in challenging conditions like underwater, hazy, and low-light environments. Techniques like using foggy images with clear object areas as ground-truth for training image enhancement models have shown effectiveness in focusing dehazing operations on target areas, leading to improved object detection accuracy in complex weather scenarios. Overall, the synergy between image enhancement and object detection is vital for overcoming visual degradation challenges and enhancing detection performance in various scenarios.
How do i implement canny edge detection?5 answersTo implement Canny edge detection, several steps need to be followed. First, a Gaussian kernel is used to reduce noise in the image. Then, the gradient magnitude and direction are calculated using the Sobel operator and approximation methods. Next, a threshold is determined using Otsu's algorithm, which can be implemented using a logarithmic unit to simplify the division operation. Finally, a hysteresis threshold is applied to remove weak edges. These steps can be implemented using various approaches, such as using CUDA C on a GPU for improved performance. Additionally, an improved execution of the Canny algorithm can be used for blurred and noisy images.
How to do object detection with AI?5 answersObject detection with AI involves using deep learning models to accurately identify and locate objects in images or videos. Various techniques have been developed to improve the accuracy and transparency of object detection systems. One approach is to use black-box explanation methods, such as the Black-box Object Detection Explanation by Masking (BODEM)method. BODEM generates multiple versions of an input image by applying local and distant masks to disturb pixels within and outside the target object. By measuring the difference in detection output before and after masking, a saliency map and heatmap are created to visualize the importance of pixels to the detected objects. Another approach is to enhance object detection performance on embedded devices by using multi-view for the same scene. This can be achieved through a system of distributed smart cameras, where each camera integrates a convolutional neural network (CNN) for detection. Implementing light networks on the distributed cameras can lead to better detection performance and reduced power consumption. Overall, object detection with AI involves leveraging deep learning models, explainable AI methods, and distributed systems to improve accuracy, transparency, and efficiency in detecting objects.
What is edge detection method in shadow detection/?4 answersEdge detection is a technique used in image processing to locate boundaries of objects within images. In the context of shadow detection, edge information is crucial for accurate detection. Various methods have been proposed to incorporate edge information into shadow detection algorithms. Olobatuyi et al. propose an edge-guided disambiguation module that uses shadow edge features to guide the generation of comprehensive shadow area features, resulting in more accurate detection results. Ge introduces a soft edge description model that describes the degree of each pixel belonging to the edges or not, which is then incorporated into a fuzzy clustering procedure for shadow detection. Halder et al. propose a novel approach to edge detection based on Richardson's extrapolation technique, which measures edge strength. Romani et al. present an iterative method based on interpolation with Variably Scaled Kernels (VSKs) for edge detection in 1D problems, and introduce a non-iterative technique for edge detection in higher dimensions.
How vision works?5 answersVision is the process of extracting behaviorally-relevant information from patterns of light that fall on the retina as the eyes sample the outside world. Non-human primates have traditionally been the preferred animal model for studying visual processing, but recent years have seen a resurgence of interest in alternative animal models such as rodents, birds, fish, and insects. These models offer simpler visual systems that are easier to understand and can provide insights into the universal and essential computational principles underlying visual processing. The brain constructs perception based not only on the information captured by the eyes but also on stored information and "guesses" made by the brain. Illusory figures and real-world challenges like occlusion and noise demonstrate how the visual system works. Researchers have increasingly turned to mice as a model for understanding the neural basis of visual perception due to the variety and sophistication of tools available for studying specific cell types and circuits.
What are the goal of object detection?5 answersThe goal of object detection is to accurately and efficiently detect instances of objects from a known class in images or videos. It involves recognizing and localizing objects by drawing bounding boxes around them. Object detection systems use extracted features and learning algorithms to achieve this. The advancement of computer vision systems, particularly with the use of deep learning techniques, has greatly improved the precision of object detection. Object detection methods aim to achieve high precision with acceptable real-time performance, making them suitable for applications such as aiding visually impaired individuals in locating everyday objects. These methods utilize various techniques such as convolutional neural networks, dropout, batch normalization, and data augmentation to enhance performance. The ultimate goal is to develop efficient and fast object detection algorithms that can accurately detect objects in images or videos.
