I need to convert those files from RGB to grayscale and should resize it but i am unable to read the file and cant convert all the files from RGB to gray at once and cant resize all the images at once and should save the converted and resized images. Can anyone help me with the coding of that please

OutputFolder = 'C:\Temp';  % Set as needed [EDITED]
dinfo = dir('*.jpg');% image extension
for K = 1 : length(dinfo)
  thisimage = dinfo(K).name;
  Img   = imread(thisimage);
  Y     = imshow(Img);
  Gray  = rgb2gray(Img);
  GrayS = imresize(Gray, [112, 92], 'bilinear');
  imwrite(GrayS, fullfile(OutputFolder, thisimage));  % [EDITED]
end
Or any other method for the resizing, see: doc imresize.
[EDITED] See the changed code for writing the changed file. Perhaps you want to modify the file name. Then you can split the file extension and the name by fileparts.
