Automatic Detection of Logos in Video and Their Removal Using Inpainting
نویسندگان
چکیده
In this paper, we propose an algorithm that automatically detects and removes moving logos in video. The proposed algorithm consists of logo detection, tracking and extraction, and removal. In the logo detection step, we automatically detect moving logos using the saliency map and the scale invariant feature transform. In the logo tracking and extraction step, an improved mean shift tracking method and backward tracking technique are used in which only logo regions are extracted by using color information. Finally, in the logo removal step, the detected logo region is filled with the region of neighborhood using an exemplar-based inpainting that can fill a large detected region without artifacts. These steps are effectively interconnected using control flags. Experimental results with various test sequences show that the proposed algorithm is effective to detect, track, and remove moving logos in video.

Automatic location and removal of video logos
Most commercial television channels utilize video logos, which can be considered as a form of a visible watermark, as a declaration of intellectual property ownership. They are also used as a symbol of authorization to rebroadcast when original logos are used in conjunction with newer logos. An unfortunate side effect of such logos is the concomitant decrease in the viewing pleasure. In this pa...
متن کاملVideo Subject Inpainting: A Posture-Based Method
Despite recent advances in video inpainting techniques, reconstructing large missing regions of a moving subject while its scale changes remains an elusive goal. In this paper, we have introduced a scale-change invariant method for large missing regions to tackle this problem. Using this framework, first the moving foreground is separated from the background and its scale is equalized. Then, a ...
متن کاملAutomatic TV Logo Detection, Tracking and Removal in Broadcast Video
TV logo detection, tracking and removal play an important role in the applications of claiming video content ownership, logo-based broadcasting surveillance, commercial skipping, and program rebroadcasting with new logos. In this paper, we present a novel and robust framework using tensor method for these three tasks. First, we use tensor based generalized gradient and the OTSU binarization alg...
متن کاملErasing video logos based on image inpainting
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. In this paper, 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 ...

The proposed system introduces a novel technique of text detection and removal from the input image as well as video called image inpainting using a cost effective computational technique. The paper discusses about inpainting problem empirically and proposes a new inpainting mechanism where the same algorithm can perform text removal from both image and video. Use of an effective morphological ...
