This paper deals with the design of a practical self-recovery mechanism for lossy compressed JPEG images. We extend a recently proposed model of the content reconstruction problem based on digital… (More)
In this paper we propose a novel scheme for semifragile self-recovery based on iterative filtering of randomly sampled image sections. The scheme exhibits very good robustness against both malicious… (More)
Intelligent monitoring is currently one of the most prominent research areas. Numerous aspects of such schemes need to be addressed by implementation of various modules covering a wide range of… (More)
This paper deals with the design of a self-embedding scheme for JPEG-compressed images. Most of existing schemes are compatible only with loss-less images. Few of them are capable of handling lossy… (More)
Annotation watermarking is a technique that allows to associate content descriptions with digital images in a persistent and format independent manner. It is commonly used in medical applications… (More)
Annotation watermarking is a technique that allows to associate textual annotations with digital images in a format independent manner. The embedded annotations are robust against common image… (More)
