Abstract
A method and apparatus for fine granular scalability encoding. The following steps are repeated, for each individual transform block in an image frame. A respective plurality of residual coefficients are decomposed for the respective transform block. A respective plurality of bit-planes or discrete quantization steps are processed for the respective transform block before decomposing coefficients for a next one of the transform blocks in the image frame.
Claims20
A method for fine granular scalability encoding, comprising the steps of:
- (a) repeating, for each individual transform block in an image frame, the steps of:
- (i) decomposing a respective plurality of residual coefficients for the respective transform block;
- (ii) processing a respective plurality of bit-planes or discrete quantization steps for the respective transform block before decomposing coefficients for a next one of the transform blocks in the image frame.
Apparatus for fine granular scalability encoding, comprising
- means for decomposing a plurality of residual coefficients for an individual transform block of/an image frame;
- scanning and coding means for processing a respective plurality of bit-planes or discrete quantization steps for the respective transform block before decomposing coefficients for a next one of the transform blocks in the image frame.
A computer readable medium having computer program code encoded thereon, wherein, when the computer program code is executed by a processor, the processor executes a method for fine granular scalability encoding, comprising the steps of:
- (a) repeating, for each individual transform block in an image frame, the steps of:
- (i) decomposing a respective plurality of residual coefficients for the respective transform block;
- (ii) processing a respective plurality of bit-planes or discrete quantization steps for the respective transform block before decomposing coefficients for a next one of the transform blocks in the image frame.
