06154493 is referenced by 88 patents and cites 9 patents.

What is disclosed is a method that includes splitting raw image data into a plurality of channels including color plane difference channels, and then compressing separately each of these channels using a two-dimensional discrete wavelet transform, the compression utilizing quantization, whereby the recovery of the compressed channel data yielding a perceptually lossless image. The method and apparatus operates on images directly in their Bayer pattern form. Quantization thresholds are defined for the quantizing which may vary depending upon the channel and DWT sub-band being processed.
