Abstract
Picture quality measurement systems and methods are provided for measuring DC blockiness within video blocks. Block boundaries are located within a test video frame. The relative AC differences within each block are measured using a reference video frame, a statistically estimated reference or a default value of the white video level divided by two. An objective DC blockiness map, a subjective DC blockiness map or both may be generated.
