How to save resized image with original filename to a folder.

Hi there, I am trying to save a resized (smaller) image to a folder. I am doing image classification and having the resized images would be helpful.   I would like to store the resized images into a folder called "resized" or something like that. Any thoughts? Thank you for any help you can offer.   Code below. Comments are from some of my trying to work it out myself.     clc clear all close all load('Train_AlexNet_Feature') load('Train_AlexNet_Label') Test_AlexNet_Feature=[]; BT50=[]; mkdir('New Folder') ds = imageDatastore('/Users/kimpitman/Documents/MATLAB/Vehicle/Test'); a=ds.Files; for i=1:length(a) [I,info] = readimage( ds , i); g=imresize(I,[227,227]); imshow(g) net=alexnet; net.Layers; layer='fc7'; F=activations(net,g,layer,'outputAs','rows'); Test_AlexNet_Feature=[Test_AlexNet_Feature;F]; SVMModel=fitcsvm(Train_AlexNet_Feature,Train_AlexNet_Label,'KernelFunction','Linear'); [label,score]=predict(SVMModel,Test_AlexNet_Feature); label=label; if label(i,:)=='1' display('This is BT-50') BT=info.Filename BT=string(BT); BT50=[BT50;BT]; imwrite(g,fName(i),'.png'); %srcFiles = dir('/Users/kimpitman/Documents/MATLAB/Vehicle/Test'); % the folder in which ur images exists %for i = 1 : length(srcFiles) %filename = strcat('/Users/kimpitman/Documents/MATLAB/Vehicle/Testcopiedimages',srcFiles(i).name); %im = imread(filename); %newfilename=strcat('/Users/kimpitman/Documents/MATLAB/Vehicle/Testcopiedimages',srcFiles(i).name); %imwrite(k,newfilename,'jpg'); %end %end %newfilename=ds.Files('/Users/kimpitman/Documents/MATLAB/Vehicle/Testcopiedimages',srcFiles(i).name); %imwrite(g,newfilename,'jpg'); %imwrite(g,ds); else display('This is not BT-50') BT=info.Filename BT=string(BT); BT50=[BT50;BT]; end end save('BT50') T=table(BT50,label); fname=sprintf('LinearTestMix159%s.xlsx',datestr(now, 'yyyymmddHHMM')); writetable(T,fname,'Sheet',1)
