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.

Image Compression Algorithm Based on Region of Interest Extraction for Unmanned Aerial Vehicles Communication

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.

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.

Modified spiht algorithm for quincunx wavelet image coding

, 2019
In this paper, an image compression method based on the Quincunx algorithm coupled with the modified SPIHT encoder (called SPIHT-Z) is presented. The SPIHT-Z encoder (coupled with quincunx transform) provides better compression results compared with two ...
