A vectorial approach to blindly decodable color image hiding

Abstract EN

A novel color image data hiding scheme, which can embed a color image into another color one is presented in this paper.

This scheme requires no knowledge of the original cover image for the recovery of the embedded image.

This scheme models the color image as a vector quantity and utilizes the spherical polar coordinates system to slightly modify the cover image to embed the data.

It can embed more data than many of the existing high capacity color image hiding techniques.

The hiding algorithm reported in this paper has shown promising results from the point of view of the embedding capacity and the quality of the cover image as well as the quality of the recovered data.
