Sharing secret images using integer single or multiple wavelet transform
Chin-Pan Huang · Journal of Communications Technology and Electronics · 2011
Integer wavelet transform or multiple wavelet transform has been found attractive in image and video applications where its scaling function(s) and wavelet(s) provide higher energy compaction in smooth (scaling) subband and smaller values of detail (wavelet) coefficients. This paper presents a study on an image sharing method applying the integer single or multiple wavelet transform and Shamir’s ( r, m ) threshold scheme that provide highly compact and easily manageable shadows for real time progressive transmission. Experimental results are given to illustrate the characteristics of this method.
