Abstract
A method for processing image or video data is performed in an image processing pipeline. Color filtered mosaiced raw image or video data is received. A one-level wavelet transform of subbands of the color filtered mosaiced raw image or video data to provide LL, HH, LH and HL subbands. The LH and HL subbands are de-correlated by summing and difference operations to provide decorrelated sum and difference subbands. Additional n-level wavelet transformation on the sum and difference subbands and the LL and HH subbands to provide sparsified subbands for encoding. LL and HH and sum subbands are recombined into standard color images e.g., red, green, and blue color components, which are subsequently processed by color correction, white balance, and gamma correction. The sparsified subbands are encoded.
