Image Compression Based on Wavelet and Quantization with Optimal Huffman Code
This paper proposes a method for the compression of color images by Haar transform, quantization and construction of minimum redundancy code using conventional Huffman coding. Wavelet compression is accomplished by decomposing the row and column of the image matrix using the Harr transform. And the reconstruction of the image is feasible just from 1/4 of the decomposed image and even 1/16 of th...
متن کاملWavelet and Curvelet Based Image Compression with Dead Zone Quantization
An image file contains huge amounts of information that requires high storage space, large transmission bandwidths and long transmission times. So it is useful to compress the image by storing only the required information to reconstruct the original image. An image can be considered as a matrix of pixel or intensity values. In order to compress an image redundancies must be evaluated, for exam...
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 کاملWavelet Based Image Compression Using Sparse Representation and Vector Quantization
Ordinary images, as well as most natural and manmade signals, are compressible and can, therefore, be well represented in a domain in which the signal is sparse. Sparse signal representations have found use in a large number of applications including image compression. Inspired by recent theoretical advances in sparse representation, we propose an image compression using wavelet, sparse represe...
متن کاملImage Compression using Haar Wavelet Transform and Huffman Coding
In modern sciences there are several method of image compression techniques are exist. Huge amount of data must be sent and stored efficiently and effectively, the aim of image compression is to scale back the size and form of image without degrading the quality retrieving the back the original image. the best Haar moving ridge transform, it's the foremost simplest among separate wavelet remode...
