A comparison of discrete cosine transform and discrete wavelet transform algorithm in watermarking against common attacks

Digital watermarking is a technique to embed additional data to digital images, audios and videos without affecting the quality of the original image. Watermark can be extracted for ownership verification or authentication. Currently, there is no comparison documented done between Discrete Cosine Tr...
