3D cameras are capable of capturing image and depth map of an object simultaneously. We propose a method to hide depth map, as a watermark, in its corresponding 2D image. 3D cameras enabled with this functionality could serve two purposes; protection

Passive depth estimation techniques with improved precision can replace active methods in 3D cameras. In this paper, we introduce accurate depth estimation from image focus using cubic degree Bezier-Bernstein polynomial. Experimental results demonstr

This paper presents a semi-fragile watermarking technique capable of both authenticating and recovering an image. The proposed approach offers choice of embedding two watermarks and is able to detect and differentiate the modifications applied on the
