Effect of JPEG compression on image watermark detection
Compression on a watermarked image can significantly affect the detection of the embedded watermark. To show that a particular watermarking scheme is robust against compression, simulation is often relied upon. In this paper, we investigate this problem analytically. We first characterize the noise introduced by JPEG compression. We then propose a maximum a posteriori (MAP) detector, analyze it...

this experimental study has been conducted to test the effect of oral presentation on the development of l2 learners grammar. but this oral presentation is not merely a deductive instruction of grammatical points, in this presentation two hypotheses of krashen (input and low filter hypotheses), stevicks viewpoints on grammar explanation and correction and widdowsons opinion on limited use of l1...
15 صفحه اولJPEG Compression Using MATLAB
Creating, editing, and generating images in a very regular system today is a major priority. The original image data generated by the camera sensor is very large to store, so the efficiency is not high. Mobile or bandwidthlimited systems become particularly cumbersome, where the object is a conservative bandwidth cost, such as the World Wide Web. This situation requires the use of efficient ima...
متن کاملJPEG Compression of Still Images
A technique known as JPEG is widely used for the compression of digital data representing photographic still images. In this article, we explain how this technique works. Appendixes give tutorial insight into several technical concepts that are involved.
