ABSTRACT:
Image data identifying multiple pixels in an image is received, and a multi-resolution hierarchical structure is created from the image data. Further, output values are calculated for the pixels in the image using a wavelet-based retinex algorithm by propagating pixel values computed at lower resolution levels of the multi-resolution hierarchy to higher levels of the multi-resolution hierarchy and refining the propagated pixel values at the higher resolution levels.
