The sub stanc e o object extra ction or the vision system o robot is image segmentation. Among lots o ruits and ve getables, there are a considerable color di erenc e b etwe en their rip e ruits and their backgrounds, yet the ruits o the same typ e are o a lmos t the same c olor. Then the distribution o color between the ripe ruits and the ba ck2 grounds is di erent in Color Sp ac e. Ba sed on the se e atures, an algorithm to extra ct ruits2 object rom images, which is ba sed on the approach o color2 sp a ce re erence list, was put orward . A color sp ac e re erence list wa s built rom ruits swatch images in the algorithm. The ruit object wa s extracted by using the list . Comp ared with other image segmenta2 tion arithmetic, this arithmetic ba se on color images, then the ba ckground will b e more cle an when
