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.

Classified Vector SPIHT for Wavelet Image Coding [PDF]
, 2006 Wavelet based image coding has been shown to be an effective method, especially at low bit rate. Two successful approaches, space-frequency quantization (SFQ) and set partitioning in hierarchical trees (SPIHT) were proposed to predict insignificant ...

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 ...

CDRWF: Compressed Domain Based Robust Watermarking Framework for Colored Images
IET Image Processing, Volume 19, Issue 1, January/December 2025.Image watermarking in the compressed domain is a highly significant research problem. The work proposed in this paper addresses the dual challenge of optimizing image compression for storage conservation and simultaneously implementing robust image watermarking for copyright protection.

IET Image Processing, Volume 19, Issue 1, January/December 2025.UAVs are widely used but have limited storage and bandwidth issues, so we propose ROIE‐UC, an image compression algorithm for UAV communication. ROIE‐UC uses SLIC and DBSCAN to segment images into ROI and non‐ROI, applying lossless and high‐ratio lossy compression, respectively, and is decompressed at the receiving end.

MODIFICATION TO SPIHT ALGORITHM USING INCREMENTAL THRESHOLD FOR IMAGE COMPRESSION [PDF]
, 2020 The Modified SPIHT represents a more efficient implementation of the SPIHT algorithm by using variable thresholds to sort the list of insignificant pixels (LIP) and the list of insignificant sets (LIS).
