Abstract:
The article gives a detailed analysis of seamless image stitching methods into a panorama from an overlapping image set. Source images usually have varying colors and luminance due to cameras` position changing. Various approaches of blending and color correction algorithms for source images are presented. This paper illustrates the optimal technic for parallel evaluation of color correction coefficients in all overlapping areas. High quality of our blending method is confirmed by color and structure similarities based on PSNR and SSIM indexes accordingly.

Keywords:
multiframe image processing, color blending, image analysis, panoramic image stitching.
