HARDWARE IMPLEMENTATION OF SATELLITE IMAGE ENHANCEMENT USING DWT LIFTING SCHEME WITH SPARTAN3 FPGA KIT
Journal Title: International Journal of Computer Science & Engineering Technology - Year 2014, Vol 5, Issue 4
Abstract
Enhancement of a digital or satellite image can be done in either of the areas viz, contrast , resolution and sharpness. In this paper we are introducing the hardware implementation of image enhancement using DWT lifting scheme. Noise removal and preservation of useful information are important aspects of image enhancement. The Discrete Wavelet Transform has been widely used in image processing, digital communications and other application fields, because the DWT can decompose the signals into different sub-bands with both time and frequency information and facilitate to achieve a high compression ratio.
