An Evolution Perception Mechanism for Organizing and Displaying 3D Shape Collections.

How to display the best view of shape collections to facilitate non-profession users is becoming a challenging problem in the field of computer vision. To solve this problem, an evolution perception mechanism for organizing and displaying shape collections (EPM) is proposed. On the one hand, the evolution tree based on Quartet analysis is constructed to effectively organize shapes from a global perspective. On the other hand, the shape snapshot method based on the view features of shapes is presented for each single shape in the evolution tree, so as to show the details of the shape from a local perspective. Moreover, the interactive display methods using the evolution trees are provided to guide users to effectively explore the shape collections. Experimental results show that EPM could provide the effective displaying ways that are close to the user's viewing.
