| 20090010546 | Edge-Guided Morphological Closing in Segmentation of Video Sequences - A method of image processing, includes receiving at least one video frame of a video sequence, the at least one video frame including at least one foreground subject and a background, and processing the at least one video frame so as to separate the at least one foreground subject from the background. The processing includes: generating a pixel mask indicating whether a pixel of the at least one video frame belongs to the foreground subject or to the background, applying morphological closing to the pixel mask, wherein the applying morphological closing includes, for each pixel of the pixel mask, conditioning a pixel value in the mask to values of neighboring pixels. The conditioning includes: determining at least edges of the at least one foreground subject in the at least one video frame; and, for the generic pixel under processing, determining the neighboring pixels based on the determined edges. | 01-08-2009 |
