Performance analysis of data hiding in thermal image using alpha blending technique

Abstract

Hiding data in an image become a very successful technique to communicate with end users, blinding the interpreter’s intention. Various algorithms have been analyzed on the basis of masking the content within the coordinates of the images or in the color of the images used. Few advanced developed complex algorithms to hide the content in the values of the colors to ensure or guarantee robustness of the data hidden. In this research, a simple technique called alpha blending is used to hide the data in an image and its impact is analyzed for different alpha values. The unavoidable impact of noise on the transmitted carrier image was formulated and studied by many researchers using various available algorithms. In this regard: the same is analyzed using alpha blending in thermal images.
