Claim 0:
1. A method for correcting grayscale of an image implemented on a computing device including at least one processor and a storage, the method comprising:
determining a first region of interest (ROI) in a first image and a second ROI in a second image;
determining a first overlapping region of the first image and the second image in the first image and a second overlapping region of the first image and the second image in the second image;
determining a first intersection region of the first ROI and the first overlapping region in the first image and a second intersection region of the second ROI and the second overlapping region in the second image;
determining the first image as a reference image;
determining a first grayscale range of the first intersection region and a second grayscale range of the second intersection region;
determining a correction slope based on the first grayscale range and the second grayscale range; and
correcting a grayscale of the second ROI in the second image based on the correction slope.
