Low-Complexity Scalable DCT Image Compression
We have developed a scalable image compression scheme with a good performance-complexity trade-off. Like JPEG, it is based on the 8 × 8 block discrete cosine transform (DCT), but...

Robust Learning of 2-D Separable Transforms for Next-Generation Video Coding
With the simplicity of its application together with compression efficiency, the Discrete Cosine Transform(DCT) plays a vital role in the development of video compression standar...

A New Deblocking Algorithm Based on Adjusted Contourlet Transform
A new postprocessing method based on adjusted contourlet transform is introduced in this paper for suppressing blocking artifacts (BA) in block-based discrete cosine transform (BD...

A Register File with Transposed Access Mode
We introduce a new register file architecture that provides both row-wise and column-wise accesses, thus allowing partitioned instructions to be used in columnwise processing with...

A jointly optimal fractal/DCT compression scheme
In this paper a hybrid fractal and Discrete Cosine transform (DCT) coder is developed. Drawing on the ability of DCT to remove inter-pixel redundancies and on the ability of fracta...
