Text-Detector Guided Video Encoding

Abstract

Systems and methods described herein for encoding of video frames based on an amount of text contained within each block of the frame. For each frame, text detection is performed to identify text contained within each block of the frame and each pixel position within the frame. The text detection outputs, for each block and pixel position, an amount of textual content with respect to a preset threshold amount. Based on the output, only the blocks and pixel positions having an amount of text content equal to or greater than the threshold amount are selected as candidates for block matching. For other blocks block matching processes are bypassed.
