چکیده

In this paper, we present an approach of using binary tree structures for efficient progressive image compression. General ideas of progressive transmission and image approximation are discussed. We also present a specific technique, which provides compression ratios comparable to the ratios of the best algorithms known in the literature. Besides, it is computationally simple and specially designed for fast progressive reconstruction of image sketches. Practical results are also present in this paper.

Intelligent scalable image watermarking robust against progressive DWT-based compression using genetic algorithms

Image watermarking refers to the process of embedding an authentication message, called watermark, into the host image to uniquely identify the ownership. In this paper a novel, intelligent, scalable, robust wavelet-based watermarking approach is proposed. The proposed approach employs a genetic algorithm to find nearly optimal positions to insert watermark. The embedding positions coded as chr...

A Lossy Colour Image Compression Using Integer Wavelet Transforms and Binary Plane Transform

In the recent period, image data compression is the major component of communication and storage systems where the uncompressed images requires considerable compression technique, which should be capable of reducing the crippling disadvantages of data transmission and image storage. In the research paper, the novel image compression technique is proposed which is based on the spatial domain whi...

Progressive Lossless Image Compression Using Image Decomposition and Context Quantization

Lossless image compression has many applications, for example, in medical imaging, space photograph and film industry. In this thesis, we propose an efficient lossless image compression scheme for both binary images and gray-scale images. The scheme first decomposes images into a set of progressively refined binary sequences and then uses the context-based, adaptive arithmetic coding algorithm ...

Progressive Image Compression Using Contourlet Transform

This paper proposes a novel progressive image compression algorithm using the nonlinear contourlet transform. Contourlets are effective in capturing directional information in images using a flexible set of basis functions that are elongated and directional. Since the contourlet transform is redundant, a wavelet based contourlet transform has been applied on the image. The wavelet based contour...

Graceful Degradation over Packet Erasure Channels through Forward Error Correction

We present an algorithm that assigns unequal amounts of forward error correction to progressive data so as to provide graceful degradation as packet losses increase. We use the SPIHT coder to compress images in this work, but our algorithm can protect any progressive compression scheme. The algorithm can also use almost any function as a model of packet loss conditions. We nd that for an expone...
