Complete labeling set for 3D-sketch with occlusion
Shizhong Liao · Computer Engineering and Applications Journal · 2009
Line labeling is an essential approach to spatial semantics representation for 3D-sketch.Almost all of the previous works converted sketches to tidy line drawings before labeling,as they used the label sets derived from perfect projections of 3D objects.This paper addresses 3D-sketch labeling problem in the blocks world,and proposes a complete labeling set for 3D-sketch with occlusion,which can be used to label 3D-sketches directly without tidying.This label set can not only realize the labeling of true 3D-sketch,but also shed new light on the semantics representation of 3D-sketch.
