Title:
背景領域および前景領域をモデリングする方法
Document Type and Number:
Japanese Patent JP4708343
Kind Code:
B2
Abstract:
A temporal sequence of images is acquired of a dynamic scene. Spatial gradients are determined using filters. By taking advantage of the sparseness of outputs of the filters, an intrinsic background image is generated as median filtered gradients. The intrinsic background image is then divided into the original sequence of images to yield intrinsic foreground images. The intrinsic foreground images can be thresholded to obtain a detection mask.
