Abstract :
A video logo is usually a declaration of the video copyright. However it sometimes causes visual discomfort due to the presence of multiple logos in videos that have been filed and exchanged by different channels. We present an approach to erase logos from video clips. Based on the histogram energy analysis of the relevant video frames, we obtain the best quality logo frame that can be easily processed in the selected region of video frames. After that, we mark the logo area in the entire sequence of frames and inpaint each frame of the video logo based on color interpolation. We describe our technique and also provide experimental results.
