Abstract :
The paper investigates the use of exact histogram specification for robust watermarking. A class of watermarks are selected such that the presence of certain groups of consecutive gray levels is considerably reduced with no visual degradation of images. The proposed technique is proven to be very resistant to many intentional and unintentional attacks.
