I have a checker board patterns with small and big rectangle shapes crossings. I want to detect only these big crossing points not small rectagular crossing using intrest operaters. Is there any option??

Try using hough() or houghlines(). What are the "small rectagular crossing"? I don't know if I see any of those. And what are "intrest operaters"?

He probably refers to "interest point detection" using "interest operators".

I don't know what that is either. I've heard of "salient point detection" like is used in SIFT and SURF. Maybe it's the same thing.
Or maybe this: https://en.wikipedia.org/wiki/Kadir%E2%80%93Brady_saliency_detector
Anyway, you might also be able to use the corner() function in the Image Processing Toolbox.
