Research on Image Color Balancing Based on Illumination Correction
Abstract:
Nowadays, image fusion is one of the common color balance method. But, the color distortion is prone to occur in the fused image. To overcome such drawbacks, a novel method based on illumination correction was proposed in the paper. First, search the identical or similar ground objects areas on both source images, and calculate the average gray of each color component in the found areas. Then, calculate each color component ratio of the average gray of the reference image to the average gray of the color cast image, and take the ratio as the adjusting coefficients of corresponding component. Finally, each color component is multiplied by the adjusting coefficients separately. The theoretical analysis and experiment results show that the proposed method has better ability in color balance.
