Find position of an object in an other image

I want to detect the position of a simple object of an image into another image. The object is like a simple rectangle of couple of overlapping rectangles with uniform color background.
I tried matlab functions of detectHarrisFeatures and detectSURFFeatures.
detectHarrisFeatures works well but fails when the pair of images have a different magnifications (change in number of pixels of the object). It also fails when there is a small disturbance (defect, hot spot, partical) in one of the image. Whereas detectSURFFeatures fails when the object is too simple (eg. just a rectangle)
Any suggestion? Thanks in advance

You might try Hu's moments which are rotation and scale invariant.
