Moving Cast Shadow Detection
Moving shadow detection is an important topic in computer vision applications, including video conference, vehicle tracking, and three-dimensional (3-D) object identification, and has been actively investigated in recent years. Because, in real world scenes, moving cast shadows may be detected as foreground object and plauge the moving objects segmentation. For example, in traffic surveillance ...
متن کاملMoving Cast Shadow Detection
1 Overview Motion perception is an amazing innate ability of the creatures on the planet. This adroitness entails a functional advantage that enables species to compete better in the wild. The motion perception ability is usually employed at different levels, allowing from the simplest interaction with the 'physis' up to the most transcendental survival tasks. Among the five classical perceptio...
متن کاملAdaptive Moving Cast Shadow Detection
Moving object detection is an important task in real-time video surveillance. However, in real scenario, moving cast shadows associated with moving objects may also be detected, making moving cast shadow detection a challenge for video surveillance. In this paper, we propose an adaptive shadow detection method based on the cast shadow model. The method combines ratio edge and ratio brightness, ...
متن کاملMoving Cast Shadow Detection Using Texture Information
In this paper, we have proposed an efficient moving cast shadow detection using texture features. Texture features are estimated using fractal dimension and is employed to discriminate between shadow region and moving foreground region. Complexity and noise reduction is achieved using wavelet transform which has not been performed before in the literature. Block-wise calculation has accelerated...
متن کاملEye movements and visible persistence explain the mislocalization of the final position of a moving target
When observers are asked to localize the final position of a moving target, the judged position is usually displaced from the actual position in the direction of motion. The short-term time course of the displacement was investigated to test theories that attribute the localization error to spatial and temporal properties of human perception or to representational momentum. It was found that br...
