Special Issue on Image security: secure imaging - is it necessary?
Editorial Special Issue on Image security: secure imaging—is it necessary? In the mathematical model of Shannon, ''the fundamental problem of communication is that of reproducing at one point either exactly or approximately a message selected at another point''. The pioneering papers of Shannon described also cryptographic coding for ensuring confidentiality. Efficient, confidential, authentic ...

متن کاملGuest Editorial Special Issue on Information Security
⎯Recently, an edge adaptive image steganographic method based on least significant bit (LSB) matching revisited (EA-LSBMR) has been proposed, which holds good visual quality and proper security under appropriate embedding rates. However, from the extensive experiments to EA-LSBMR, we find that the discrete Fourier transform (DFT) spectrum of pixelpairs differences histogram still reveals the pr...

متن کاملSpecial Issue on Image Processing and Analysis
Conceptualizing away the sketch processing details in a user interface will enable general users and domain experts to create more complex sketches. There are many domains for which sketch recognition systems are being developed. But, they entail image-processing skill if they are to handle the details of each domain, and also they are lengthy to build. The implemented system’s goal is to enabl...
