iam having this issue how can is resolve this Undefined function or variable 'M'. Error in Untitled (line 39) MW = perform_cu​rvelet_tra​nsform(M, options);

clear all; close all; clc; v = VideoReader('foreman.mp4'); tic numFrames = v.NumberOfFrames;

k=1; while k<=numFrames frame=read(v,k); frame=imresize(frame,[256 256]); frame=double(frame); [a b z]=size(frame);

frame = frame/255.0; sigma = .05; redChannel = frame(:, :, 1); greenChannel = frame(:, :, 2); blueChannel = frame(:, :, 3);

xr = redChannel + sigma*randn(size(redChannel)); xg = greenChannel + sigma*randn(size(greenChannel)); xb = blueChannel + sigma*randn(size(blueChannel));

noisyRGB = cat(3,xr,xg,xb);

MW = perform_curvelet_transform(M, options); hh =MW ; redMF = hdenoise(xr,hh); g greenMF = hdenoise(xg,hh); blueMF = hdenoise(xb,hh); rgbFixed = cat(3, redMF,greenMF,blueMF);

imshow([frame,noisyRGB,rgbFixed],[0,1]) k=k+1;

end toc

Upload your code

In the above code you didn’t mention the variable M which causes the error.

[rubab ali]

cann u please tell me the command for M__ as i m using these commnads from this link for calling curevelet transform function http://www.numerical-tours.com/matlab/denoisingwav_6_curvelets/#8

 P.S - I have no experience in curvlet transformation

But all I am sure of is you haven’t defined M in your script but your using at the end which causes the error
