An efficient, secure color image coder incorporating Color-SPIHT (C-SPIHT) compression
and partial encryption is presented. Confidentiality of the image data is achieved by …

This paper introduces a new implementation of wavelet packet decomposition which is
combined with SPIHT (Set Partitioning in Hierarchical Trees) compression scheme. We …

An embedded partial encryption technique of compressed color images based on chaos is
proposed. Modifying the bit values of different types which are obtained by Color-SPIHT …

The embedded zero-tree wavelet (EZW) coding algorithm is a very effective technique for
low bitrate still image compression. In this paper, an improved EZW algorithm is proposed to …

This paper presents the Secure Shape and Texture SPIHT (SecST-SPIHT) scheme for
secure coding of arbitrarily shaped visual objects. The scheme can be employed in a privacy …

Video display systems include frame memory, which stores video data for display. To reduce
system cost, video data are often compressed for storage in frame memory. A desirable …

This paper proposes a method for progressive lossy-to-lossless compression of four-
dimensional (4-D) medical images (sequences of volumetric images over time) by using a …

This paper describes an echocardiogram coding method that takes into account the
visualization modes in order to compress efficiently the echocardiogram, a methodology to …

This paper proposes the application of various types of highlight extractors method to
perceive the airplane utilizing the satellite picture. Acknowledgment of article (Aircraft) in a …

In this paper, the compression of multispectral images is addressed. Such 3-D data are
characterized by a high correlation across the spectral components. The efficiency of the …
