Experiments: Three groups of real datum (images) are tested. 
The first group is composed of an object; the second image has 
three objects; and the third image contains many objects. The 
size of images is 512X512 pixels with 8 biU/256 gray level. 
These industrial parts are designed by GEMS system, and then 
are manufactured in factory. Finally these objects are put in 
experimental platform. Three groups of real images are captured 
by CCD camera (type: COSMICAR) when the cameras was
