Recognition of channel logo from analog video: An embedded realization

This paper presents the hardware implementation of the algorithm for recognizing the channel logos from the analog videos in real time in a commercially available DSP platform. This solution can be used for different value added services for connected TV like providing EPG on real time, real time TV viewership analysis, user view time analysis. This paper mainly focuses on the issues in optimization of dual core embedded realization of the algorithm that is performing efficiently in an x86 platform. The optimization techniques we have used can save up to 150% of CPU cycles and also the proposed ARM DSP communication made the system an efficient one.
