Hierarchical mask creation for intelligent image coding using saliency maps
International Journal of Advances in Telecommunications, Electrotechnics, Signals and Systems, 2016 In this paper we analyze basic mask creation methods for intelligent image coding using saliency maps. For saliency maps based image coding we use specific extension of SPIHT algorithm called SM SPIHT related to region of interest encoding but extending ...

Partial Encryption on SPIHT Compressed Images [PDF]
, 2009 Recently, Multimedia security paradigm has shifted towards encryption techniques combined with compression systems to meet the constraints of wireless networks. Several techniques of encryption with compression have been proposed to reduce processing time, but either they are insecure or computationally intensive.
