Applications of Semisupervised and Active Learning to Interactive Contour Delineation

We describe a novel application domain for semi supervised and active learning algo rithms namely that of intelligent interactive contour extraction It is well known that ob ject delineation is an ill posed problem unless guided by the human or by apriori constraints and models We focus on user steered extrac tion which has been the focus of investiga tion in a large volume of work in computer vision We will discuss how this problem can be naturally translated to a semi supervised and active learning problem and we will de scribe our work so far towards investigating the issues involved
