Intelligent Scissoring for Interactive Segmentation of 3D Meshes
نویسنده
چکیده
Many algorithms and tools exist for the segmentation of 3D meshes. However, they are labor intensive and lack the simplicity of 2D image segmentation systems, limiting them to a small set of expert users. This paper introduces a new segmentation tool which aims for accurate and flexible interactive mesh segmentation, yet maintains an easy-to-use interface suitable for novices and experienced users alike. Extending the stroke based interface of 2D intelligent scissoring, 3D intelligent scissoring tackles the difficulties that arise from three dimensionality while at the same time gives the user more freedom than in previous systems. Intelligent scissoring obtains desirable segmentations easily and interactively, and presents many possibilities for future work within the field.

Mesh scissoring with minima rule and part salience
This paper presents an intelligent scissoring operator for meshes. Unlike common approaches that segment a mesh using clustering schemes, we introduce a method that concentrates on the contours for cutting. Our approach is based on the minima rule and part salience theory from cognitive theory. The minima rule states that human perception usually divides a surface into parts along the concave d...

The segmentation of tomographic image data is an important prerequisite for a meaningful vi-sualization in medicine. To circumvent diicul-ties related to automatic approaches, we suggest interactive segmentation which includes the knowledge of a user more eeciently. Using intelligent scissors, as presented in 1] for the 2D case, we suggest 3D lters for the calculation of the cost matrix, an aut...
