Abstract:
1. A method for embedding a watermark into a video, the method comprising: converting, by an image management computing device, at least one predetermined size of a video frame, of the video, from a Red Green Blue (RGB) color space to a YUV color space; dividing, by the image management computing device, a first chrominance component of the video frame into a plurality of blocks of a predetermined size wherein each of the plurality of blocks comprises a plurality of pixels, wherein each of the plurality of pixels is associated with a pixel value; selecting, by the image management computing device, the plurality of blocks based on a predetermined size of the watermark; associating, by the image management computing device, at least one pixel in the watermark with at least one pixel in the selected plurality of blocks; embedding, by the image management computing device, the watermark corresponding to the selected plurality of blocks to obtain a processed first chrominance component, wherein the embedding comprises: determining, by the image management computing device, a minimum pixel value of a column of a block in the plurality of blocks and replacing a pixel value of the block with the minimum pixel value of the column of the block when a binary value of a corresponding watermark pixel is zero; creating, by the image management computing device, a processed YUV video frame by combining a Y component and a second chrominance component of the video frame with the processed first chrominance component of the video frame; and converting, by the image management computing device, the processed YUV video frame to a RGB video frame.
