MEDICAL IMAGE COMPRESSION USING HYBRID CODER WITH FUZZY EDGE DETECTION [PDF]
Medical imaging techniques produce prohibitive amounts of digitized clinical data. Compression of medical images is a must due to large memory space required for transmission and storage.

Compressive Data Hiding: An Unconventional Approach for Improved Color Image Coding
Traditionally, data hiding and compression have had contradictory goals. The former problem adds perceptually irrelevant information in order to embed data, while the latter removes this irrelevancy and redundancy to reduce storage requirements. In this

Improving SPIHT-based Compression of Volumetric Medical Data [PDF]
Volumetric medical data (CT,MR) are useful tools for diagnostic investigation however their usage may be made diffcult because of the amount of data to store or because of the duration of communication over a limited capacity channel.

Classified Vector Spiht Forwavelet Image Coding
Wavelet based image coding has been shown to be an effective method, especially at low bit rate. Two successful approaches, space-frequency quantization (SFQ) and set partitioning in hierarchical trees (SPIHT) were proposed to predict insignificant wavelet coefficients.

MEDICAL IMAGES COMPRESSION BASED ON SPIHT AND BAT INSPIRED ALGORITHMS
There is a significant necessity to compress the medical images for the purposes of communication and storage. Most currently available compression techniques produce an extremely high compression ratio with a high-quality loss.

Optimized Progressive Coding of Stereo Images Using Discrete Wavelet Transform [PDF]
In this paper, a compression algorithm is introduced which allows the efficient storage and transmission of stereo images. The coder uses a block-based disparity estimation/ compensation technique to decorrelate the image pair.

JAVA-based effective implementation of an image compression tool [PDF]
Tato diplomová práce se zabývá problematikou ztrátové komprese digitálních obrazových dat. Ztrátová komprese obecně zavádí určité zkreslení do výsledné reprezentace obrazu. Toto zkreslení by mělo být nerušivé nebo v lepším případě nepozorovatelné.
