Abstract


Digital watermarking is a technology used to identify the original or duplicate. In this paper we have compressive approach for digital video watermarking is introduced, were watermark image is embedded in to the video frame each video frame is decomposed in to sub images using Morphological Filters, Automatic Color Enhancement technique [ACE ] Transform is applied for each block. Combining the two transform improved the performance of the watermark algorithm. The scheme is tested by various attacks. Experimental result shows private key for embedding and a public key for detection, it shows the robustness against a wide range of attack such as Gauss ion noise, salt & pepper Noise, median filtering, rotation, cropping etc. The Proposed scheme is tested using number of video sequences .its experimental result shows high imperceptibility where there is no noticeable difference between the watermark video frame and original video frame.


Keywords


Digital Watermark, Morphological Filters, Automatic Color Enhancement Technique [ACE], Watermark Embedding, Watermark Extraction.
