In this paper we propose a Region of Interest (ROT) based coding strategy for JPEG-LS that has the additional ability of providing effective rate controlled image compression.  ...  We provide experimental results to compare the performance of the proposed rate-control algorithm with the state of the art near lossless rate control schemes.  ...  ROT region is compressed with the idea of maintaining a good visual image quality and the non-ROT region is 'blanked-out' completely, therefore no rate-controlled compression of the overall image.  ...

Pawel Korus, Andrzej Dziech
2014 IEEE Transactions on Information Forensics and Security  
Based on the derived theoretical model, we propose a procedure for optimization of the overall reconstruction quality given constraints on the desired target tampering rate, and the required quality level  ...  In this study we addresses the problem of adaptive self-embedding, where the reconstruction quality is controlled individually for different fragments of a digital image.  ...  At first, the decoder recovers the quality descriptor q. Based on the assigned quality profiles, it then regenerates the reference information of authentic image regions.  ...
