F=griddedInterpolant(...,'cubic');
interpolatedData=F(...);

Can you please give me more details. For examples, if one of the images is : A=imread('Translated frame_120 with respect to frame_1.png'); the size of A is 448 by 901. How can I apply the function u mentioned on these data. Thank you

Can't you simply use imresize()?

Hey, Can anyone suggest how can I interpolate image using cubic spline interpolation (For any general images)?

scale = 1/10;
r = size(YourImage,1);
c = size(YourImage,2);
[R, C] = ndgrid(1:r, 1:c);
newrv = linspace(1, r, floor(r*scale));
newcv = linspace(1, c, floor(r*scale));
[NewR, NewC] = ndgrid(newrv, newcv);
for channel = size(YourImage,3) : -1 : 1
  newImage(:,:,channel) = interp2(R, C, YourImage(:,:,channel), NewR, NewC, 'spline');
end

newImage = cast(newImage, class(YourImage));

imshow(newImage)
