Removing photometric discrepancy on seam-lines of 3D model textures

and achieve natural and continuous color transition across the texture seam-lines.We propose a new photometric processing method of face-wise Poisson blending

which is based on the standard Poisson image editing approach combined with color transfer techniques.First

we regard the texture triangle on images as the processing unit

and the color transfer parameters as the unknowns; then the Poisson equations set is constructed according to the edge adjacent topology on the triangular mesh; after that

the color transfer parameters are resolved using global least square; at last

color correction is locally performed with the global solution.Our method assures the smooth and continuous color transition besides the seams and simultaneously remoral of the global color difference between images more effectively.Compared with standard pixel-wise Poisson blending method

our procedure has the advantages in computing and implementation

which is more appropriate for seamless texture processing on complicated models.Even more

our approach has a better effect in global color difference correction and transition.Theoretical analysis and experiments prove the superiority of our method.
