I have no idea. I don't even know if integralImage is an array or some function you have. Or even if it's a MATLAB function. Perhaps you should ask in the ImageJ forum. I can't even determine if this is a MATLAB question or not.

Yes, It's a function of matlab . to changean image into integral image to save computation time. but it's showing error for the case of dimention.

It is not in any of my toolboxes:
Your search - integralImage - did not match any documents.
Suggestions:
Make sure all words are spelled correctly.
Try different keywords.
Try more general keywords.
Try fewer keywords.
What toolbox is it in. What do you see if you do this on the command line:
>> which -all integralImage
