In the present work, an image is decomposed into image blocks. In this scheme a low bit rate still image compression is performed by compressing the indices of vector quantization and residual codebook is generated by using Modified Fuzzy Possibilistic C-Means with Repulsion and Weighted Mahalanobis...

An image compression coding method of a digital image transmission system utilizes a known vector quantization process. In the method, at the transmitting end the block (13) to be coded is divided into quadrants (14); each quadrant is su... J Virtamo,S Valli - US 被引量: 44发表: 1997...
Interval arithmetic (IA) can enhance vector quantization (VQ) in image-compression applications. In the interval arithmetic vector quantization (IAVQ) reformulation of classical VQ, prototypes assume ranges of admissible locations instead of being clamped to specific space positions. This provides the VQ...

Image compression using vector quantization (VQ) results in highly correlated indices. The correlation between these indices is used to reduce the bits needed to represent them. This is done by many index compression algorithms such as the Hu and Chang, search order coding (SOC), and switching ...
