Abstract


Data hiding is, mainly related to the possibility of perceiving the presence of an object by means of human sight. There are many ways, by which perceptual model can be incorporated into data hiding system to control perceptibility of data. In this work author implements, model for simple adjustment of a global embedding strength, based on cover image. Whitening filter is used at decoder which helps to de-correlate samples of received image, and improve performance of system. Work encompasses Watson perceptual model.
