Method and system for facilitating color balance synchronization between a plurality of video cameras as well as method and system for obtaining object tracking between two or more video cameras

摘要

The present invention relates to a method for facilitating color balance synchronization between a plurality of video cameras (10a, 10b, 10c) within a system of video cameras The method comprises: detecting an object in a video sequence captured by a video camera (10a, 10b, 10c) in the system; determining an object color histogram for the detected object; updating a camera specific reference color histogram using said determined object color histogram; and determining one or more camera specific color histogram compensation coefficients by comparing the camera specific reference color histogram with a system reference color histogram. The present invention further relates to a system for facilitating color balance synchronization between a plurality of video cameras as well as a video camera (10) being connectable to a network of video cameras for facilitating color balance synchronization between a plurality of video cameras.
