Wavelet Transform Techniques for Image Resolution Enhancement: A Study
P Bagawade Ramdas, S Bhagawat Keshav, Mikkilineni Pradeep - · 2012
Images are being used in many fields of research. One of the major issues of images is their resolution. In this paper we are studying different image resolution enhancement techniques that use Wavelet Transform (WT). Basis functions of the WT are small waves located in different times. They are obtained using scaling and translation of a scaling function and wavelet function Therefore, the WT is localized in both time and frequency. In this paper we are comparing different image resolution enhancement techniques those using Wavelet Transform.
