Hi,
I have 3 pictures, try to write a code to select an area on my a3 picture with getrect, and then crop my a1 and a2 pictures following the same selected area. I wrote this :
clear all
%Tentative de crop
a11 = imread('well5recovered.tif'); %recovered
a1 = rgb2gray(a11);
a22 = imread('well5original.tif'); %original
a2 = rgb2gray(a22);
a3 = imread ('well5 cell.tif');
imshow (a3,[]);
rg2=round (getrect); %selection zone
imgf_a1=imcrop (a1,rg2); %crop a1
figure
imshow (imgf_a1);
imgf_a2=imcrop(a2,rg2); %crop a2
figure
imshow (imgf_a2);
I dont know why I dont have the same dimension for my cropped a1 and a2. A1 is way smaller than a2 and none of them seem to be the exact same size of what I had selected on a3 with getrect.
Thank you for your help!

Depending on the resolution image after cropping, the dimensions will change. If you want to have the dimensions of the cropped images same, consider resizing them in to your desired dimensions using imresize. Read about imresize.
