A Novel Approach to Moving Edge Detection Using Cross Entropy
نویسنده
چکیده
We propose a moving edge extraction method using the concept of entropy and cross-entropy, in which the crossentropy concept is applied to dynamic scene analysis. The cross-entropy concept provides enhancement of detection for the dynamically changed area. We combine the results of cross-entropy in the difference picture (DP) with those of entropy in the current frame so that we can effectively extract moving edges. We also propose the moving edge extraction method by combining the results of cross-entropy and those of Laplacian of Gaussian (LoG).

A Novel Method for Moving Objects Detection Inspired by Frog's Visual Characteristics
The detection of moving objects is the hot topic of computer vision researches now. On this subject, we propose a novel method to detect moving object in surveillance videos based on the visual features of the frog eyes. This method is divided into three steps; first, to extract the moving regions using Frame Difference and Spatial-temporal entropy methods; second, to establish the edge map by ...
متن کاملMotion detection by a moving observer using Kalman filter and neural network in soccer robot
In many autonomous mobile applications, robots must be capable of analyzing motion of moving objects in their environment. Duringmovement of robot the quality of images is affected by quakes of camera which cause high errors in image processing outputs. In thispaper, we propose a novel method to effectively overcome this problem using Neural Networks and Kalman Filtering theory. Thistechnique u...
