Fuzzy Recognition Based Intra Frame Error Concealment for Block Based Images

L Ruilan,Zhu Xiuchang(Image Processing & Image Communication Lab,Nanjing Universityof Posts & Telecommunications,Nanjing,210003,China)  
A new technique for fuzzy recognition based error concealment(FRBEC) on the block-based images is proposed aimed at gray level images.The fuzzy recognition is applied to fuzzy classify for the results of surrounding pixel matching.Then,the corresponding correction is processed to modify the results of the forgoing classification.The developed pixel correction is processed to modify the pixels of the inaccurately-covered blocks with the smooth texture,and pixel re-matching is processed aimed at those with the complex texture.Experimental results show the effectiveness of the proposed method for the images with complex texture and fine details.The subjective effect is satisfactory and the PSNR is higher.
