OPTIMIZING MEMORY READS WHEN COMPUTING VIDEO QUALITY METRICS

Abstract:

Techniques to optimize memory reads when computing a video quality metric are disclosed. In some embodiments, an application-specific integrated circuit for computing video quality metrics includes a set of caches configured to store neighbor pixel data for edge width searches of pixels comprising a frame of a video being analyzed for a video quality metric and a kernel configured to receive corresponding neighbor pixel data for pixels comprising a current processing block of the frame from a subset of the set of caches and simultaneously perform edge width searches for pixels comprising the current processing block to determine corresponding pixel edge width values used for computing the video quality metric.
