Definitions for "Spatial compression"
a compression method that removes redundant data within any given image. For example, a field of blue in a picture would be stored as one large blue area rather than many individual blue pixels.
See intra-frame compression.
Image compression that is performed in the context of a single frame. This compression technique takes advantage of redundancy in the image to reduce the amount of data that is required to accurately represent the image. Compare temporal compression.
