Abstract
A foreground extracting method is provided. The foreground extracting method includes: generating a plurality of sampling images; detecting contours from the sampling images to generate a plurality of contour images including a current frame and a previous frame; comparing first positions of a first plurality of pixels in a first decision-making area of the current frame with second positions of a second plurality of pixels in a second decision-making area of the previous frame; determining directions from the second positions to the first positions and distances between the first positions and the second positions; excluding, from the first decision-making area, at least one pixel of the first plurality of pixels in response to the distance of the at least one pixel being less than or equal to a preset critical magnitude.
