Abstract
A system for encoding a video stream into a processed video signal that includes at least one image, includes a pattern detection module for detecting a pattern of interest in the at least one image and identifying a region that contains the pattern of interest when the pattern of interest is detected, based on an analysis of the image in a plurality of domains. An encoder section, generates the processed video signal and wherein, when the pattern of interest is detected, a higher quality, such as a higher bit allocation or higher computational processing, is assigned to the region than to portions of the at least one image outside the region.
Claims6
A method for encoding a video stream into a processed video signal, the video stream including at least one image, the method comprising:
- generating, via a device, a plurality of region detection decisions in a corresponding plurality of domains including at least one transform domain containing transformed image data generated based on a transformation of the at least one image and at least one untransformed domain containing untransformed image data;
- detecting, via a device, a detected region in the at least one image based on a comparison of the plurality of region detection decisions;
- when the detected region is detected, assigning a higher quality to a portion of the image, based on the detected region.
