A deblocking algorithm based on PDE
Wanchen Li · Information technology newsletter · 2009
In order to solve the problem of huge image information,image compression is an indispensable step in image transmission.The block-based discrete cosine transform(BDCT)is used by most of the international standards for image and video compression.The major drawback in BDCT is the blocking artifacts at low bit rates.In this paper,the ideas of deblocking algorithms are introduced.A deblocking algorithm based on PDE is emphatically introduced.
