The transformed signal provides information about the time and the frequency. Therefore, wavelet-transformation contains information similar to the short-time-Fourier-transformation, but with additional special properties of the wavelets… A. Mallat, Stephane G., “A Theory for Multiresolution Signal Decomposition: The Wavelet Representation”, IEEE Transactions on Pattern Analysis and Machine Intelligence, Vol. 11, No. Image Denoising Based on Wavelet Analysis for Satellite Imagery 3 4 Wavelets A better solution is to use wavelets. A function ψ(x) is a wavelet if it satisfies these conditions. ψ(x)dx = 0 ˆψ(ω) 2 ω dω C ψ < The second condition is necessary to ensure that a function can be reconstructed from a…
