| Abstract: | Three geometric platforms, namely: ACIS, CAS.CADE and PARASOLID are reviewed briefly. Their development interface, data structure, main functions and features are analysed. Finally, the future trends of CAD/CAM development platform are summarized. Key words CAD/CAM development platform, interface,data structure,function, feature Zhang Hongcai Department of Automatic Control,Northwest Polytechnical University,Xi'an 710072 Abstract This paper analyses the influence of scale factor on moment invariant features in discrete,constructs a new moment invariant with both scale,translation and rotating invariance.In simulation experiment,we recognize the images using new moment invariant,its successful rate is 95%,but old moment invariant is only 70%,therefore the results show that new moment invariant is valuable. |
