METHOD FOR REMOVING BLOCKING ARTIFACT INCLUDED IN IMAGE ENCODED BY BLOCK DISCRETE COSINE TRANSFORM TO EFFECTIVELY REPRODUCE THE IMAGE

摘要

A kind of purpose: method, it receives the edge of image and is provided to the amount that effectively reproduction one receives image and reduce calculating for include blocking artifact in the image of a coding by BDCT (Block Discrete Cosine Transform) removal not will be deleted by removing blocking artifact, be used to remove blocking artifact and handle reception image in real time. Construction: it is received by the image of a coding of BDCT. The frequency response characteristic for receiving image is measured. It is mobile by least one pixel in column and line direction to receive image, is measured by the frequency response characteristic of mobile image. When receive image frequency response characteristic and by the difference between the frequency response characteristic of mobile image be more than a preset range when, a high fdrequency component of image is removed.
