MATLAB: I need a code for Haar wavelet transform. doit4mehaar waveletno attempt Am currently working on image processing, am using Haar Wavelet transform for the feature extraction, i need a good working code on for it. Thank you. Best Answer You can use wavedec2() with either wavelet name 'haar', or 'db1'load woman;J = 4; % level of the MRA[C,S] = wavedec2(X,J,'haar');See the help for appcoef2() and detcoef2() for how to pull out the approximation and detail coefficients.
