Abstract
Embodiments include systems and methods of determining block edge location in video. In one embodiment, a system includes a block edge map generator configured to generate a binary block map, the block map having indicators representing the locations of block edges in a first direction, a histogram generator configured to accumulate the indicators to form a block edge histogram, the peaks of the histogram corresponding to block edge locations in the image, a low-pass filter to low-pass filter the block edge histogram and form a filtered histogram, a peak locator configured to identify the peaks of the filtered histogram, and a peak refiner configured to refine locations of peaks located in the filtered block edge histogram based on the identified peaks and peaks in the block edge histogram, the refined peak locations indicative of block edge locations, and further configured to provide block locations.
