A flexible polygon representation of multiple overlapping regions of interest for wavelet-based image coding
Image transmission over low-bandwidth channels can be speeded up if the image coding mechanism supports regions of interest (RoIs). By such a scheme, image parts not belonging to ...

On the security of the SARI image authentication system
In this paper we investigate the image authentication system SARI, proposed by C.Y. Lin and S.F. Chang [1], that distinguishes JPEG compression from malicious manipulations. In pa...
