This paper presents a rapid inversion method for 3D apparent density based on separation and continuation of potential field. The new method is carried out in the following three steps. Firstly, the gravity field on the plane is separated by a cutting method into several parts corresponding to strata of different depth. Secondly, by the way of downward continuation, the field resulted from different strata is respectively reduced to a plane corresponding to its depth.

文中提出了一种基于位场分离与延拓的视密度快速反演方法：首先应用场分离的切割法对平面上的重力场进行不同深度层源的切割分离；然后运用大深度向下延拓方法将各层的场延拓至相应的深度；最后反演出各深度层的密度。

Based on the two face images of the same person at front and half-profile view and an MPEG4 3D generic face model, we estimate the poses of the face at these two images and establish their 2D mesh models. Multiple views of the same face can be synthesized by image interpolation and warping, meanwhile occlusion problems are solved reasonably.
