Exploring Gradient Information in the Background Subtraction Task
نویسنده
چکیده
Background subtraction is one of the fundamental problems where its solutions can be applied to the other segmentation problems as well. The reported techniques often rely on intensity information to differentiate background pixels from the foreground ones without consider any relation between pixels. To improve the differentiation ability, this paper introduces additional information to be used base on pixel gradient. The analysis given states that the threshold for gradient difference can be selected based on the threshold used for intensity difference. At the end, the experimental results show sufficient improvements of incorporating gradient information in the background differencing task.

متن کاملA Hierarchical Approach to Robust Background Subtraction using Color and Gradient Information
We present a background subtraction method that uses multiple cues to robustly detect objects in adverse conditions. The algorithm consists of three distinct levels i.e pixel level, region level and frame level. At the pixel level, statistical models of gradients and color are separately used to classify each pixel as belonging to background or foreground. In region level, foreground pixels obt...

We present a new contour-based background-subtraction technique to detect people in widely varying thermal imagery. Statistical background-subtraction is first used to identify local regions-of-interest. Within each region, gradient information in the foreground and background are combined to form a contour saliency map. After thinning, an A* path-constrained search along watershed boundaries i...
