Lossless-by-Lossy Coding for Scalable Lossless Image Compression [PDF]
This paper presents a method of scalable lossless image compression by means of lossy coding. A progressive decoding capability and a full decoding for the lossless rendition are equipped with the losslessly encoded bit stream. Embedded coding is applied

Доклады Белорусского государственного университета информатики и радиоэлектроники, 2019 The synthesis method of paraunitary filter banks based on the quaternion algebra (Q-PUBF) for computing structures constrained by fixed point arithmetic is proposed. Synthesis problem using method of Lagrange multipliers is solved. It is shown that the Q-

An index coding algorithm for image vector quantization
, 2012 [[abstract]]This paper presents a lossless index-coding algorithm for image vector quantization. Using the concept of dynamic tree coding, the method can encode the output index map of a memoryless vector quantizer efficiently without introducing any ...

THE PROBLEM OF CONTOURS IN TRANSFORM IMAGE CODING [PDF]
, 2008 Object contours contribute to a large extent to the perceived quality of an image but are typically quite hard to compress. As a matter of facts, many coding algorithms fail to describe efficiently this information.

Advances in predictive wavelet transform image coding [PDF]
In this work, it is shown that a fractal image coding can be placed in a conventional predictive framework by using a wavelet representation. This has the significant advantage of simplifying decoding by avoiding iteration and of relating the technique ...

Lossless image coding based on fractals
, 2005 In some kind of applications, such as in space image research, every detail of an image can be important. To send the information more efficiently over a network, the image will be compressed and in the former applications that must be done in a lossless
