How to rename an image after processing with different parameters?
I have a sequence of images and I would like to perform dilation on each of them with different dilation parameters. Then, I would like to save the processed images with new name including both the old name and the corresponding dilation parameter. My codes are as follows. ``` Input_folder = Output_folder = D = dir([Input_folder '*.jpg']); Inputs = {D.name}'; Outputs = Inputs; % preallocate %print(length(Inputs)); for k = 1:length(Inputs) X = imread([Input_folder Inputs{k}]); dotLocations = find(Inputs{k} == '.'); name_img = Inputs{k}(1:dotLocations(1)-1); image1=im2bw(X); vec = [3;6;10]; vec_l = length(vec); for i = 1:vec_l %se = strel('disk',2); fprintf(num2str(vec(i))); se = strel('diamond',vec(i)); %imdilate im = imdilate(image1,se); image2 = im - image1; Outputs{k} = regexprep(Outputs{k}, name_img, strcat(name_img,'_', num2str(vec(i)))); imwrite(image2, [Output_folder Outputs{k}]) end end As it can be seen, I would like to apply dilation with parameters 3,6 and 10. Let us assume that an image has as name "image1", after processing it, I would like to have "image1_3", "image1_6" and "image1_10". However, I am getting as results "image1_3", "image1_6_3" and "image1_10_6_3". Please, how can I modify my codes to fix this problem?

Input_folder =
Output_folder =
S = dir(fullfile(Input_folder,'*.jpg'));
for ii = 1:numel(S)
F = S(ii).name;
X = imread(fullfile(Input_folder,F));
I = im2bw(X);
[~,N,E] = fileparts(F);
V = [3;6;10];
for jj = 1:numel(V)
se = strel('diamond',V(jj)); %imdilate
J = imdilate(I,se);
Y = I - J;
G = sprintf('%s_%d%s',N,V(jj),E);
imwrite(Y,fullfile(Output_folder,G))
end
end
