This paper,taking its handling in the English version of Qian Zhongshu s novel"Fortress Besieged" as a case study,points out that intertextual signals should be heeded and that the principle of optimal relevance should be observed respectively in the process of its recognition and transference.

Application of marked point registration in non-contact surface measurement of large dimension sheet parts;

A novel missing phase interpolation algorithm for the branch cut and the marked point

It used the relational matching to get the counterpoints of marked points based on the topology and introduced the Rodrigues parameters to describe the transition matrix.

Methods: Twenty X-ray cephal images of oral-maxillafacial deformation cases were collected to identify 17 landmarks in every image,both by CACAS automatically and experts manually.

In one way,landmarks were automatically idetified by CACAS,then the coordinates and parameters were analyzed automatically.

Common tools based on landmarks in medical image elastic registration are the thin plate spline(TPS).

Study on the Location Standard of Skeletal Landmarks on Three-Dimensional Reconstructive Images in Facial Asymmetry;

Manifold learning algorithm based on weighted landmark points;

Objective To develop the computerized automatic cephalometric analysis system(CACAS) on base of the technique for automatic identification of landmarks exploited before and test the validity of measurement by CACAS in clinic.

Target location is a crucial part of 3D shape measurement, because it determines the measuring precision of system to a great extent.
