A fast algorithm for the computation of 2-D forward and inverse MDCT
A fast algorithm for computing the two-dimensional (2-D) forward and inverse modified discrete cosine transform (MDCT and IMDCT) is proposed. The algorithm converts the 2-D MDCT an...

A perceptual metric for blind measurement of blocking artifacts with applications in transform-block-based image and video codin
In this paper, we analyze the formation of blocking artifacts as a result of quantization of the discrete cosine transform (DCT) coefficients. These artifacts are known to be the ...

An Adaptive De-Blocking Algorithm Based on MRF
One of the major drawbacks in block-based discrete cosine transform (BDCT) is the blocking artifacts at low bit rates. In this paper, an adaptive deblocking algorithm based on Mar...

Improved POCS-Based De-blocking Algorithm for Block-Transform Compressed Images
This paper presents a postprocessing technique based on the theory of projections onto convex sets (POCS) to reduce the blocking artifacts in low bit rate BDCT-coded images. In the...
