Abstract: Digital Image Watermarking, in recent times has seen a huge surge of professional work due to the skyrocketing usage of digital media. In this paper we present a competitive survey of existing watermarking techniques. This paper surveys the features and concepts pertaining to the two popular watermarking algorithm types and analyzes them to evaluate with metrics such as Time complexity, PSNR values and similarity measure of watermarks based on implementation i.e. A) Spatial based techniques (under which we analyzes LSB modification, correlation based and CDMA based techniques) and b) Transform based techniques (DCT and DWT based techniques). We have also studied the effects of different types of noises on each method.
Keywords: Image Watermarking, lsb, Correlation, Cdma, DCT, DWT.
