Abstract:

A frame alignment algorithm is proposed using the (7,4) Hamming code correction to resist these attacking operations. In this algorithm, the watermark is extracted by identifying watermarked frames. The simple linear iterative clustering (SLIC) superpixels method is used to extract the frames' natural characteristics X, which is a 7-bit binary sequence representing the clustering centers obtained using SLIC via preprocessing and quantization. The approach takes advantage of (7,4) Hamming code correction that can hide three bits of the target code S by modifying only one bit. The watermark is then embedded into the video containing alignment marks with DCT-SVD decomposition. Experimental results show that the proposed approach can resist attacks such as frame dropping, frame insertion and recoding. It is also robust against common signal processing operations.

Key words: targeting codes, frame dropping, recoding, video watermarking
