A Method for Compression of Solar Image using Integer Wavelet Transform
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2014, Vol 2, Issue 12
Abstract
Compression is becoming a very important method for reducing the redundancy in the images. The use of larger DWT (discrete wavelet transform) basis functions or wavelet filters produced distortion in the reconstructed image. It takes a longer compression time. This paper proposes a new technology which consist of pre-processing, IWT (integer wavelet transform), SPIHT (Set Partitioning in hierarchical trees). The integer wavelet transform reconstruct the original image without any losses. This algorithm is tested on the solar images captured by the satellite system. This experimental result shows improved compression performance, PSNR and also reduces the compression time.
