Good Quality and High Image Compression using DWT-DCT Technique
Journal Title: International Journal of engineering Research and Applications - Year 2018, Vol 8, Issue 6
Abstract
The issue of minimizing the amount of data needed to denote the digitized image is addressed by image compression. It is specially used for compression of images, where tolerable degradation is needed. The world has found itself among large amount of data due to the significant technology growth and presence into Digital Age. Dealing with such massive information can often introduce some difficulties. The compression reduces the size of the image in bytes without corrupting the image quality to unacceptable level. When the image size is reduced, various images are saved in particular allocated disk or memory space. It also minimizes the time needed to upload or download the images in web pages. This research work have been aimed to develop an efficient image compression for improving compression ratio and PSNR value based on DWT-DCT technique is designed to improve the performance and to reduce the memory consumption of the compression system.
