Abstract:
A solution for detecting a streak in a JPEG image is disclosed that includes an extraction system for extracting a DC value from each cell block in the compressed image; an identification system for identifying a peak DC value in each rank of cell blocks within the compressed image; and an analysis system for analyzing the peak DC values to determine if a streak exists in the compressed image.
