Rohini B. Dhekale, B. D. Jadhav, P. M. Patil . Satellite Image (Multispectral) Enhancement Techniques in Wavelet Domain: An Overview. International Journal of Computer Applications. 112, 11 ( February 2015), 16-20. DOI=10.5120/19711-1476
Satellite images are used in many applications like military, forecasting, astronomy, and geographical information. Satellite images have to face spatial and spectral resolution problems due to scattering, atmospheric conditions, etc. , also they have poor perception. This limitation of resolution needs to be overcome before further processing. The goal of image resolution enhancement is to improve specific features of an image for its correct representation. Better resolution is obtained by applying enhancement techniques on blurred and noisy images. In this paper various image enhancement techniques under wavelet domain like WZP, DWT, and DT-CWT are discussed. This paper also gives selection of suitable enhancement technique
