ABSTRACT:
In some embodiments of the present invention, quantized frequency coefficients of a matrix of spatial data are obtained. Blocks of frequency coefficients that will be zero-valued after quantization are identified. Only frequency coefficients belonging to other blocks are calculated explicitly using the spatial-to-frequency transform.
