Abstract
A method, computer system, and a computer program product is disclosed for encoding a sequence of color frames. The method includes a processor obtaining a sequence of color frames and rendering a first frame of the sequence in at least three components, each component representing a different color value. For each of the at least three components, the processor performs a wavelet transform on the first frame, initializes a significant points list and a list of insignificant sets to create an individual spatial tree of the list of insignificant sets for each component, searches all of the at least three components to identify a most significant bit in the first frame, and creates a consolidated significance map with all the color components for the first frame by searching the individual spatial tree for each component. The processor then obtains this significance map and utilizes the significance map to encode the first frame. The processor retains the significance map in memory as a key frame significance map and retains the first frame, or a color transform of the first frame, in memory, as a key frame.
