Abstract:

TV logo is embedded in complex background, and usually has hollow and translucent characteristics. There are many defects in the conventional TV logo detection techniques such as the complexities of image features extraction and matching algorithm as well as the characteristic dimension curse, so this paper proposes a method based on compressive sensing to quickly and efficiently identify the TV logo. This method directly processes raw pixels, not only avoiding the difficulty of features extraction, but also having good robustness for hollow and translucent logos. Experiment shows that when identifying TV logo in a single frame, the average recognition time is within 35ms, while recognition accuracy rate can reach more than 98%.

Key words: compressive sensing, TV logo, video detection
