Hello,
I have a vector that I am using reshape() to create images matrices and show it using imagesc() function every one second; however, it shows a blank images. The result of two classifiers is in Class_T and Class_F. First subplot shows image produced from Class_T, the second subplot shows image produced from Class_F, and the third one shows both.
Does anyone know how can I fix this issue? The code is as follows:
Lx = length(X2); % the number of rows 512
Ly = length(Y2); % the number of columns 512
X_F = []; Y_F = []; Class_F = [];
X_T = []; Y_T = []; Class_T = [];
Class_T = (Score_T_Test(:,2)>0.5)&(Score_T_Test(:,2)>=Score_F_Test(:,2));
Class_F= 0.5*((Score_F_Test(:,2)>0.5)&(Score_T_Test(:,2)<Score_F_Test(:,2)));
for i = 1:length(Z2) %Z2=number of images
subplot(1,3,1)
imagesc(reshape(Class_T((i-1)*Lx*Ly+1:i*Lx*Ly),Lx,Ly)), colormap('gray')
title('T Segmentation')
subplot(1,3,2)
imagesc(reshape(Class_F((i-1)*Lx*Ly+1:i*Lx*Ly),Lx,Ly)), colormap('gray')
title('F Segmentation')
subplot(1,3,3)
Im_Class = max([Class_T Class_F],[],2);
imagesc(reshape(Im_Class(end-Lx*Ly+1:end),Lx,Ly)), colormap('gray')
title('Segmentation')
pause(1)
end
Your help is appreciated.

Check the indices which you have used inside imagesc(). I suspect, the indices are not upto the mark.

Your subplots 1, 3, 2 and 1, 3, 3 have invalid code. The semi-colon is not valid syntax there.
