Lossless, near-lossless and lossy adaptive coding based on the lossless DCT
This report proposes a new coding method, which realizes lossless, near-lossless and lossy coding with a unified single algorithm. The method is based on a lifting-structured loss...

Wavelet coding of volumetric medical datasets
—Several techniques based on the three–dimensional (3-D) discrete cosine transform (DCT) have been proposed for volumetric data coding. These techniques fail to provide lossles...

Optimum word length allocation for multipliers of integer DCT
Recently, the integer DCT (Int-DCT), which has the rounding operations in the lifting structure, is attracting many researchers' attention as an effective method for DCT base...

Efficient Representation and Decoding of Static Huffman Code Tables in a Very Low Bit Rate Environment
The lossless entropy coding used in many image coding schemes often is overlooked as most research is based around the lossy stages of image compression. This paper examines the r...

A New Bit-Plane Entropy Coder for Scalable Image Coding
Compression ratio and computational complexity are two major factors for a successful image coder. By exploring the Laplacian distribution of the wavelet coefficients, a new bit ...
