Abstract

Embodiments of the present application provide an apparatus and method for detecting a color checker in an image; wherein, the apparatus includes: an extracting unit configured to extract sliding window features of sliding windows at multiple positions from an input image by using a predefined sliding window; a selecting unit configured to select, by using multiple predefined sliding window templates, a sliding window having a minimum distance from each sliding window template from the sliding windows at the multiple positions and take it as a matched sliding window of the sliding window template; and a determining unit configured to determine segmentation lines of colored squares of a color checker in the input image according to a matching result of each sliding window template. With the method and apparatus of the embodiments of the present application, the color checker in the input image may be automatically detected based on features of independent RGB channels and a geometric structure of the color checker, which has a faster speed and better robustness relative to other method.
