Apparatus and method for detecting color checker in image

A method for detecting a color checker in an image, comprising:

• extracting sliding window features of sliding windows at multiple positions from an input image using a predefined sliding window;
• selecting, 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 as a matched sliding window of the sliding window template;
• and
• determining segmentation lines of colored squares of the color checker according to a matching result of each sliding window template.
