How to Calculate Wavelet Coefficient?
Wavelet Coefficient calculator uses Detail Wavelet Coefficient = int(Scaling Function Expansion*Wavelet Expansion Function*x,x,0,Integer Index for Linear Expansion) to calculate the Detail Wavelet Coefficient, The Wavelet Coefficient formula is used to calculate the numerical values obtained from the wavelet transform of a signal or an image and it represents the strength or magnitude of the high-frequency components present in the image at different scales and orientations. Detail Wavelet Coefficient is denoted by d_{j}[k] symbol.
How to calculate Wavelet Coefficient using this online calculator? To use this online calculator for Wavelet Coefficient, enter Scaling Function Expansion (f_{s}[x]), Wavelet Expansion Function (ψ _{j,k}[x]) & Integer Index for Linear Expansion (k) and hit the calculate button. Here is how the Wavelet Coefficient calculation can be explained with given input values -> 160 = int(2.5*8*x,x,0,4).
