Point distribution models are used in image understanding . You can use it to model two-dimensional or three-dimensional objects from the real world. Its strength unfolds in objects that can deform in a fluid way, such as: B. Facial features.

Create a PDM model

You create a point distribution model for a particular object by collecting hundreds of images of that object in different deformations. A PDM consists of a certain number of two-dimensional or three-dimensional points. Now every point in every image is placed in the same place on the object. By analyzing the mutual correlation of the points, one obtains the movement of the points during deformation.
