An Algorithm to Analyze of Two-dimensional Function by using Wavelet Coefficients and Relationship between Coefficients

Wavelets are regarded by many as primarily a new subject in pure and applied mathematics. Perhaps one of the most common applications of wavelet is in signal processing. In this study we obtain an algorithm to analyze and synthesize a signal or two-dimensional function s = f(t) by using two-dimensional wavelet method. We consider a sample point (t_i,j,s_i,j) includes a value s_i,j = f(t_i,j) at height s_i,j and abscissa (time or location) t_i,j. We propose, obtaining an algorithm of two-dimensional wavelet decomposition to estimate a function by using MATLAB software for computing wavelet coefficients. Some relationships between wavelet coefficients are investigated.
