A METHOD FOR CONTROLLING TRACKING USING A COLOR MODEL, CORRESPONDING APPARATUS AND NON-TRANSITORY PROGRAM STORAGE DEVICE

摘要

A method for controlling tracking using a color model is disclosed. The method comprises obtaining a window in a second frame of a video image corresponding to a window in a first frame of the video image using a tracking algorithm in a tracking mode, wherein each pixel in the video image has at least one color component; characterized by defining a background area around the window in the first frame; assigning a pixel confidence value for each pixel in the second frame according to a color model; assigning a window confidence value for the window in the second frame according to the pixel confidence values of pixels in the window in the second frame; if the window confidence value is greater than a first confidence threshold, selecting the tracking mode; and if the window confidence value is not greater than the first confidence threshold, selecting a mode different from the tracking mode.
