Embodiment Construction
[0050] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the present invention will be further described below through specific embodiments and accompanying drawings.
[0051] figure 1 It is the non-rigid point set registration flow chart based on structural information described in the present invention, which includes the following parts:
[0052] 1) Carry out CPD registration with a localized optimization operator for the two input point sets, and obtain the globally optimal point set correspondence after matching.
[0053] 2) Obtain the preliminary stroke classification result of the data point set according to the point set correspondence relationship obtained in step 1).
[0054] 3) After step 2) is executed, each stroke corresponds to a set of template points and a set of data points, and localized CPD registration is performed for these two sets corresponding to each stroke (that is, localized optimiz...
