how can I resolve the error related to corr2 in my code ??

4 views (last 30 days)
my code is:
clc;
clear all;
close all;
tic;
i1 = imread('G:\testing\abrupt\ed1ac\1.jpg');
i2 = imread('G:\testing\abrupt\ed1ac\2.jpg');
c = corr2(i1,i2);
toc;
and the following error is coming :
[a,b] = ParseInputs(varargin{:});
Error in correlation (line 7) c = corr2(i1,i2); please tell me how to solve this issue??

corr2 takes matrices as inputs. In your case i1, i2 are 3D matrices. Try
c = corr2(i1(:,:,1),i2(:,:,1));
Alos note that i1 and i2 should be of same size. If they are not of same size, use imresize to make them into same dimensions.
