Answer 1

How about

upperLeft = grayImage(1:rows/2, 1:columns/2);

and so on?

[tina jain]

Undefined function 'grayImage' for input arguments of type 'double'

this is the error

tina, what did you call your image variable? grayImage was just an example - you were supposed to replace it with actual variables.

[rows, columns, numberOfColorChannels] = size(whateverYourImageIsCalled);
r1 = int32(rows/2);
c1 = int32(columns/2);
r2 = r1+1;
c2 = c1+1;
upperLeft = whateverYourImageIsCalled(1:r1, 1:c1);
upperRight = whateverYourImageIsCalled(1:r1, c2:end);
lowerLeft = whateverYourImageIsCalled(r2:end, 1:c1);
lowerRight = whateverYourImageIsCalled(r2:end, c2:end);
