Recognition of trademarks from sports videos for channel hyperlinking in consumer end
Tanushyam Chattopadhyay, Aniruddha Sinha · 2009
In this paper authors have proposed a system to automatically recognize the Trademarks from sports video for channel hyperlinking in client end. In this method we have used the output of Set Top Box (STB) video stream in YUV 4:2:2 formats as input to our application. In this work we have first localized the text regions using some characteristic of text and then recognized the trademark using the shape invariant features and color features from the restricted trademark database. Experimental results show that the proposed approach can work in real time in any commercially available DSP platform and can mark the trademarks in the video successfully. The system on different type of sports videos gives a recall rate of 86.6% and a precision rate of 85.42%.
