Sparse Volume Segmentation for 3D Scans
First Claim
1. A computer readable medium embodying instructions executable by a processor to perform a method for sparse volume segmentation for 3D scan of a target, the method comprising:
- learning prior knowledge;
providing volume data comprising the target;
selecting a plurality of key contours of the volume data;
building a 3D spare model of the volume data given the plurality of key contours;
segmenting the volume data using the 3D sparse model; and
outputting a representation of the volume data based on the segmentation using the 3D sparse model.

Abstract
A computer readable medium is provided embodying instructions executable by a processor to perform a method for sparse volume segmentation for 3D scan of a target. The method including learning prior knowledge, providing volume data comprising the target, selecting a plurality of key contours of the image of the target, building a 3D spare model of the image of the target given the plurality of key contours, segmenting the image of the target given the 3D sparse model, and outputting a segmentation of the image of the target.
