WebDescription. x = waverec2 (c,s,wname) performs a multilevel wavelet reconstruction of the matrix x based on the wavelet decomposition structure [ c, s] and the wavelet specified by wname. See wavedec2. x = waverec2 (c,s,wname) is equivalent to x = appcoef2 (c,s,wname,0). x = waverec2 (c,s,LoR,HiR) reconstructs x using the specified lowpass … Websizex = size(X) sizex = 256 256 sizec = size(c) sizec = 1 65536 val_s = s val_s = 64 64 64 64 128 128 256 256 Algorithm For images, an algorithm similar to the one-dimensional case is possible for two-dimensional … ravi patel orlando ortho

WebAug 8, 2013 · Xrec = waverec2 (C,S,'db4'); max (max (abs (X-Xrec))) wkeep () and wkeep2 () -- wkeep2 is for image data. It is a convenience function that is used internally in other functions of the Wavelet Toolbox to retain the appropriate output from convolutions. An example is the use of wkeep2 () inside of iswt2.m. Sign in to comment. ravi pathmanathan leicester
