摘要: Interactive mesh and image cutting refers to the process of extracting meaningful parts from an input mesh or image and involving a little user interaction to indicate user intention. It is an active research area in computer graphics and image processing in recent years. In this talk I will present some of our recent work in this area. Specifically, we propose a constrained random walks algorithm that adds constraints to the random walks procedure and thus allows for a variety of intuitive user inputs, and develop a unified framework for interactive mesh or image cutting that supports three typical user inputs and also their combinations: foreground/background seed inputs, soft constraint inputs, and hard constraint inputs. The varieties of user inputs make the cutting process intuitive, flexible and effective. Experimental results show that our algorithms are fast, reliable, and capable of producing good results reflecting user intention and geometric attributes.
