ACTIVE ATTENTIONAL SAMPLING METHOD FOR ACCELERATING FOREGROUND DETECTION FROM VIDEO, AND COMPUTER-READABLE RECORDING MEDIUM FOR THE SAME

摘要

The present invention applies a foreground probability map and a sampling mask according to temporal characteristics, spatial characteristics, and frequency characteristics of an input image to a foreground detection algorithm that performs operations on a pixel-by-pixel basis to remove a background from an input image, To an active focused sampling technique capable of improving detection speed. According to the present invention, when an active focused sampling mask is generated for an input image, only the portion corresponding to the sampling mask is processed for the corresponding frame, so that foreground detection is achieved, and the foreground detection speed is greatly improved. In other words, compared with the conventional foreground detection method performed on a pixel-by-pixel basis, the processing speed can be improved to about 6.6 times without deteriorating the detection performance, and the full-HD image can be detected in real time .
