An original and interactive approach to efficiently and accurately segment bony structures from CT image data is presented and evaluated. Based on the JULIUS software framework, different image filtering algorithms were tested and a new 3D interactive segmentation module using 3D texture mapping was developed. The approach was tested for CT image data from 7 different craniofacial cases. It was shown that efficiency could be improved while quality of the segmentations was stable compared to manual segmentation.

In this thesis, we improve the standard 3D medical image interactive segmentation workflow. Drawing from the field of Active Learning, we propose a method for automating the process of deciding where the user should provide input next for optimally improving the segmentation. Specifically, we evaluate a given intermediate segmentation by constructing an uncertainty field over the image domain based on a multitude of segmentation quality metrics. We then find the plane that intersects with maximal uncertainty, and present it to the user for segmentation as an active batch query. We demonstrate the method through two embodiments, one using the Random Walker segmentation algorithm, and the other using the 3D Livewire method as seen in the software tool, TurtleSeg. We show that in both implementations, our method makes better decisions than user intuition and greatly reduces user interaction time.

The authors survey a recent technique in computer vision called Interactive Co-segmentation, which is the task of simultaneously extracting common foreground objects from multiple related images. They survey several of the algorithms, present underlying common ideas, and give an overview of applications of object co-segmentation.
