QUALITATIVE RECOGNITION OF 3D OBJECTS FROM RANGE IMAGE
Uan M · Acta Automatica Sinica · 1993
In this paper, a new 3D object qualitative representation called Qualitative Description Graph (QDG) is presented. This symbolic rep esentation can separate effectively the objects with occlusion and simplify greatly the identi ication of objects in complex scenes. To improve the recognition efficieney, s recursive scheme integrating 'purifying' with 'searching' is proposed. Several experiments show that this ap(?)roach is effective, robust and efficient.
