Title:
CODEBOOK PRINCIPLE-BASED EFFICIENT VIDEO MOVING OBJECT DETECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2021/136001
Kind Code:
A1
Abstract:
A Codebook principle-based efficient video moving object detection method, used for mainly eliminating system time delay caused by memory management, simplifying the calculation process of a Codebook method, and accelerating an operation speed. The method specifically comprises: acquiring a video frame from a video signal source in real time, wherein the video frame consists of pixels, the pixels consist of several channel components, and each channel of each pixel has a histogram having a fixed size; when the pixel histogram of a new image frame is updated, using an increment factor as a histogram increment unit; and for a newly received image frame, determining whether each pixel in an image is a foreground or a background, and before receiving a next frame image, multiplying the increment factor by a forgetting factor, i.e., T=T*R. The histograms are directly compared during detection, and the efficiency is higher.
