Capsule Endoscopy Image Coding Using Wavelet-Based Adaptive Vector Quantization without Codebook Training

The amount of image data generated by capsule endoscopy is so large that data compression is desirable. In our compression scheme, a codebook (CB) replenishment mechanism is incorporated in a wavelet-based adaptive vector quantizer (VQ). The progressive SPIHT coding is used to meet the quality deman...
