Preprocessing filtering method for H.264 video coding standard

摘要

The present invention by providing a digital filtering, preprocessing methods for quality improvement in H.264 Video Coding Standard and to address the problem of noise reduction and complexity resulting from the input image of the video equipment. ; Thus, the present invention is that the adjacent pixels of the previous block in the image obtained from the image capture system based on H.264 and presented to the filtering and pre-treatment method using a correlation that is characterized by noise (noise) generated from the input image obtained by removing the filter for the current pixel block according to the degree of similarity to the neighboring pixels between the current block. ; Thus, the present invention can be applied for low-cost image pickup device that is the case by the deterioration of the input image generation in a wide range of low bit rate compression encoding technique or a high-speed processing is desired.
