WebJan 27, 2024 · The inter-pixel relations in the time dimension (t) direction is the temporal redundancy (inter-frame redundancy). Similarly, the spatial redundancy is the inter-pixel relations in an individual frame in the (x, y) space (intra-frame redundancy). The main purpose of video compression techniques is to encode the original video with fewer bits.
