Quality Assessment of Colour Image Compression using Haar Wavelet Transform
Journal Title: INTERNATIONAL JOURNAL OF ENGINEERING TRENDS AND TECHNOLOGY - Year 2012, Vol 3, Issue 3
Abstract
Images require substantial storage and transmission resources, thus image compression is advantageous to reduce these requirements. This paper covers some background of wavelet analysis, data compression and how wavelets have been and can be used for image compression. The paper examines a set of wavelet functions (wavelets) for implementation in a still image compression system and discusses important features of wavelet transform in compression of still images, including the extent to which the quality of image is degraded by the process of wavelet compression and decompression. The effects of different wavelet functions, image contents and compression ratios are assessed.
