To enhance security of three-dimensional images, an inter-view local texture analysis (ILTA) based stereo image reversible data hiding method is presented. Due to low accuracy of existing predictors, two novel predictors are proposed to improve the prediction precision. In the first predictor, a texture analysis model is built by using ILTA, in which the texture similarity between a pair of matched...
As the popularity of three dimensional video, security of stereo image has become an evident issue to be solved. This paper presents a disparity based stereo image reversible data hiding by using histogram shifting, which can recover the original stereo image from marked stereo image without any distortion. Inter-correlations between left and right views of stereo image are utilized to predict pixels...
