An Effective Method of Secret-Fragment- Visible Mosaic Video Generation Using HAAR Wavelet Transformation
Swapnil Patil [6] | A. A. Deshmukh [3]
Abstract: In this paper present a method for creating a video mosaic, a two dimensional arrangement of small source videos (tiles) that suggests a larger, unified target video. The mosaic video is the video which looks similar to arbitrarily selected target video is yielded by dividing the secret video. In the existing system work on the mosaic images is already done by number of researcher using different methods. Now here we are working on videos to make it mosaic by using HARR Wavelet Transform. A method for creating a video mosaic by using HARR Wavelet Transform consist of, a two dimensional arrangement of small source videos (tiles) that suggests a larger, unified target video. In this paper, we have suggested the transform domain method for digital video watermarking for embedding invisible watermarks behind the video. It is used for copyright protection as well as proof of ownership. In this paper, we first extracted the frames from the video and then used frequency domain characteristics of the frames for watermarking. In this paper, we have specifically used the characteristics of the Discrete Cosine Transform for watermarking and calculated different parameters. We also introduce a dynamic programming algorithm that automatically chooses the smaller tiling sub-sequences from a large collection of candidate source video sequences to best match the target video. After the selection process, the color in the tiling videos is automatically adjusted to better suggest the target video. Finally, our method also supports the use of different tiling shapes. The information required for recovering the secret image is embedded into the created mosaic video by a lossless data hiding scheme using a key. Good experimental results show the feasibility of the proposed Method. .
