The Research Committee in the Department of Computer Science and Information held a seminar entitled "New Blind Color Watermarking Technique based on DCT-DWT and Quadtree".

The seminar was presented by Dr. Wael Khider who suggested a new way to disguise a watercolor image in another color image, where the HSV (Hue, Saturation , Value) color model is the ideal successful model.

He then proposed a new scheme for embedding and masking high-capacity colored watermarks in a frequency domain based on image tree segmentation. Quadtree decomposition is used to split the DCT-DWT subdomains of the Hue component of the host image. 

The new color-blind image watermarking technique uses a new technology to embed the color Hue image element into the wavelet by processing it using a quad tree corresponding to the host image. The experimental results support the superiority of our scheme over existing methods and the robustness and data hiding ability.
