Gyrator wavelet transform based non-linear multiple single channel information fusion and authentication

Gyrator wavelet transform

“…It can be claimed that GWT yields better output in some of the optical image processing applications, such as edge enhancement. It is hoped that GWT would broaden the scope of GT and hence can be used in various optical image processing applications, as already reported in some works [27][28][29][30]. An optical set-up has been suggested for possible optical implementation of this transform.…”

“…In our previous work, for the first time, GWT was introduced as a new tool for dealing with the optical information processing applications [27]. Since then, various reports have emerged that employ this tool for different applications [28][29][30]. In this paper, we study the properties of GWT from mathematical point of view.…”

Optical information security systems based on a gyrator wavelet transform

“…First, an asymmetric cryptosystem based on multiple-image fusion and authentication is presented [30]. Second, an asymmetric cryptosystem based on group-multiple-image encryption and watermarking is described [31].…”

“…Furthermore, I am grateful to Elsevier B. V. and the Optical Scociety of America for the permission to reprint the paper referred to in [30] and [31], respectively.…”

“…Recently, a new DWT-based image encryption has been proposed where an encrypted original image is transformed into a resulting cover image-like encrypted image instead of a noise-like encrypted image [29]. Further, a gyrator wavelet transform has been introduced and developed to achieve better applications in optical information security [30,31].…”
