Title: FOREGROUND SEGMENTATION METHOD AND DEVICE
Abstract:
A foreground segmentation method and device, the method comprising: respectively extracting local characteristic information about two input images, and matching key points according to the extracted local characteristic information; screening a mismatching point from matching points among obtained key points to obtain all the correct matching points; performing cluster analysis to obtain, from all the correct matching points, a characteristic point group on a foreground object; and according to the obtained characteristic point group, using an image segmentation method to obtain the foreground object in the image. The embodiments of the present invention improve the accuracy of a foreground object in an image, reduce foreground processing time, and improve the efficiency of image processing.
