Claim 0:
1. An apparatus comprising:
at least one memory;
instructions; and
processor circuitry to execute the instructions to:
process features extracted from first and second downscaled image frames to determine block classifications for respective blocks of the first and the second downscaled image frames, the features including at least one of (i) spatial and temporal features based on data from a luminance layer of the first downscaled image frame and the second downscaled image frame, or (ii) information on luminance differences between rows and columns of pixels of the second downscaled image frame;
generate a map based on the block classifications, the map including values representative of amounts of change associated with blocks of the second downscaled image frame and corresponding blocks of the first downscaled image frame; and
adjust a quantization parameter of a full-scale image frame based on the map, the full-scale image frame corresponding to the at least one of the first or the second downscaled image frames.
