Satellite Image Compression using Discrete wavelet Transform
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2017, Vol 17, Issue 2
Abstract
Image compression is one of the main task in saving storage requirements and conserving transmission Bandwidth. In this paper, an Image compression based on wavelet transform is proposed to reduce the bit rate for compressing satellite Images. The variable bit rate is obtained using variable thresholding of wavelet coefficients. Some images from LANSAT 8 are compressed and the image quality metrics bits perpixel, PSNR is verified. The proposed method performs better for low bitrate applications in terms of PSNR.
