摘要：This paper aims to compute the effect of the different watermarking techniques on a proposed scheme of image copyright protection. This scheme depends on image association principle rather than image data modification. Hence, it is intended to support the developed technique with essential study to approve the validity with convenient measures and performance criteria. The effect of watermarking is classified in accordance to image format types. In this, distinguished rates of image disturbance are supposed to be injected as noise in either single component or multi components of image colour space attributes. The conducted experiment studied the effect of this noise on output associated signature using neural networks and Matlab. The study also extends to cover some suggestions that can be used as a diagnostic process to discover the intruding techniques from one side. And from the other side is to recover images from the resulting disturbed output resulting from traditional processing, like size and rotation affections towards robustness characteristic preservation.
