ABSTRACT:

Image processing based on the continuous or discrete image transforms are classic techniques. The image transforms are widely used in image filtering, data description, etc. Considering that the Haar and morlet functions are the simplest wavelets, these forms are used in many methods of discrete image transforms and processing. Wavelets transforms are widely' used in many research areas and its advantages over conventional Fourier transform as it takes less time and individual wavelet functions are localized in space but Fourier transform cannot. In this study, similarities and dissimilarities between wavelet transform and Fourier transform are also discussed. Furthermore, the applications of wavelet transform in many areas like face recognition, fingerprint analysis, image compression and image denoising are discussed.
