A Detail Preserving Vector Median Filter Based on Texture Analysis
Résumé
A texture detail preserving vector filter is proposed to remove impulsive noise in color images. By computing the texture complexity of the local neighborhood centered at each pixel according to the texture analysis of the color image, the proposed method classifies the local neighborhood into smooth region or texture one. For smooth regions and texture regions, different smoothing strategies are performed. For a smooth region, more smoothing is needed, whereas for a texture region the amount of smoothing should be controlled by its texture complexity. Experimental results show that the proposed method obviously outperforms the classical VMF both in noise suppression and in texture and detail preservation.
