Lossless-by-Lossy Coding for Scalable Lossless Image Compression

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 to largeamplitude coefficients in a wavelet transform domain. The other wavelet coefficients are encoded by a context-based entropy coding. Th...

Lossless and Lossy Data Compression

Data compression (or source coding) is the process of creating binary representations of data which require less storage space than the original data 7; 14; 15]. Lossless compression is used where perfect reproduction is required while lossy compression is used where perfect reproduction is not possible or requires too many bits. Achieving optimal compression with respect to resource constraint...

Medical Image Analysis and Achieving Compression using Hybrid Lossless and Lossy Compression Technique

Medical images like X-ray, CT or MRI produces visual representation of inner body structure. To recognize and name the exact character of a disease or a problem of human health condition, medical imaging is best method for them. For storage & transmission purpose there exist a need for compression of these images. Current compression schemes provide a very high compression rate with a considera...

An image multiresolution representation for lossless and lossy compression

We propose a new image multiresolution transform that is suited for both lossless (reversible) and lossy compression. The new transformation is similar to the subband decomposition, but can be computed with only integer addition and bit-shift operations. During its calculation, the number of bits required to represent the transformed image is kept small through careful scaling and truncations. ...
