cell array to array conversion

Sir,

I'm getting the above error and the code is shown below. Please help me my project.

for i=2:n
    gray2{i}=rgb2gray(im_cropped{i});

       d2{i}=im2double(gray2{i});
       c=d2{i};
               targets(:,i)=c(:);
          i=i+1;

      end

Subscripted assignment dimension mismatch.

Error in image_net (line 28)
        targets(:,i)=c(:);

Error in Imageclickback (line 20)
image_net(im_cropped,a,a2,a3,a4);

Error in img_net (line 23)
Imageclickback(a,a2,a3,a4,n);

Your im_cropped are not all the same size as each other. Or possibly they are, but you had previously initialized targets to a different number of rows.

Agreed. I seriously doubt you even need to have two giant cell arrays containing all the images anyway. Why not just get the image and cropped image and process them right then and there? Why save them in cell arrays? I virtually never do that.

Next, setting i=i+1 inside a for loop that is itself setting i is not a good idea. Whatever you set i to will be overwritten once the next iteration begins. Anyway, use k. Most MATLABers don't use i and j for loop iterators since those represent the imaginary variable.
