Abstract
The present invention relates to a computer-implemented method, system and computer readable medium for embedding a watermark into a video and extracting a watermark from the original or copy of the watermarked video. The method comprises converting a video frame from RGB color space to YUV color space. Divide a chrominance component into plurality of blocks. Select plurality of blocks based on size of watermark. Associate a pixel in the watermark with selected plurality of blocks. Embed the watermark corresponding to selected plurality of blocks wherein embedding comprises replacing a first pixel value of the block with maximum value of first column of the block if binary value of the corresponding watermark pixel is one or else replace with minimum value. Combine Y component and chrominance components resulting processed YUV video frame and convert it to RGB video frame. Extract the watermark substantially in a reverse process.
