COMPUTER-IMPLEMENTED METHOD MODELING BACKGROUND IN SEQUENCE OF FRAME OF VIDEO

摘要

PPROBLEM TO BE SOLVED: To model a background in a sequence of frames of a video by a computer-implemented method. PSOLUTION: For each frame, this method detects static corners using an array of pixels of the frame, and extracts, for each static corner, features from a window of pixels around the static corner. For each static corner, a descriptor is determined from the corresponding features. Each static corner and corresponding descriptor is stored in a memory, and each static corner is classified as a background or foreground according to the descriptor to model a background in the video.
