Parallax-Based Color Correction in Image Stitching
Chao Wang, Zeyu Gao, Qiankun Lu · 2020
As an effective image preprocessing method, color correction is widely used in the field of image stitching. However, due to the changeable visual environment, parallax often occurs in mosaic images. So far, there are few algorithms dealing with color correction under parallax situation. And most color correction methods produce poor results in images with parallax. This paper introduces a color correction algorithm which can also be applied in the case of parallax in image mosaic. We use VFC algorithm, color hue information and iterative calculation to obtain better color correction results. Compared with existing algorithms, it has the wider range of applications. The experiments show that our method has faster time efficiency and better results.
