Wavelet Based Compression for Image Retrieval Systems

چکیده
In this paper, the investigation on using the ZTE /modified SPIHT wavelet based compression algorithm for the image retrieval system is presented. As ZTE/modified SPIHT algorithm codes an image into multi-layer bitstreams, the base layer and enhancement layer bitstreams, it provides superior benefits to the retrieval system compared to other compression methods. Since the base layer bitstream is analogous to a thumbnail image, it eliminates the redundancy of data. Moreover, the enhancement layer bitstream also allows fast transmission that enhances the performance of retrieval systems.

Implementation of VlSI Based Image Compression Approach on Reconfigurable Computing System - A Survey
Image data require huge amounts of disk space and large bandwidths for transmission. Hence, imagecompression is necessary to reduce the amount of data required to represent a digital image. Thereforean efficient technique for image compression is highly pushed to demand. Although, lots of compressiontechniques are available, but the technique which is faster, memory efficient and simple, surely...
متن کاملImage Compression Method Based on QR-Wavelet Transformation
In this paper, a procedure is reported that discuss how linear algebra can be used in image compression. The basic idea is that each image can be represented as a matrix. We apply linear algebra (QR factorization and wavelet transformation algorithms) on this matrix and get a reduced matrix out such that the image corresponding to this reduced matrix requires much less storage space than th...

متن کاملIntelligent 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...
متن کاملAn improved image retrieval algorithm for JPEG2000 compressed images
In this paper, we are interested in studying the impact of the compression on the performances of some wavelet-based retrieval systems. Firstly, we show that the quantization operation of JPEG2000 has a negative effect on the performance of these contentbased image retrieval systems for a given feature extraction method. Moreover, in this work, we aim at designing a novel retrieval strategy in ...
