Welcome to HaYDWT a Video Watermarking Software. HaYDWT is a video watermarking and video tools software. It is developed to demonstrate the newly developed video watermarking algorithm. It embeds a binary watermark image into video frames using a randomly generated masking image. It can also extract the embedded image with the help of key image.

In addition there are several video and image tools. Video format conversion, calculating PSNR of image, video and any files are included. Video conversion from CIF, QCIF, gray_CIF, gray_QCIF(all are YUV format) to AVI format is possible. It can calculate PSNR of one frame or entire frames and write down to a text file.
