Abstract
The invention provides a plurality of compression schemes that provide improved compression ratios. An exemplary embodiment compresses each pixel by one of a plurality of different entropy-based compression schemes based upon a probability cost analysis. Another exemplary embodiment compresses each pixel based on a hybrid context formed using a plurality of compression schemes for improved probability determination, and thus improved entropy encoding.
