Abstract

Mesh surface saliency detection is an important preprocessing step for many 3D applications. The salient region can be used to find the objects that are important on 3D surface, the benefits of saliency detection in the 3D domain include mesh simplification, registration, segmentation, compression, etc. This paper proposes a novel saliency detection method by diffusing the shape index field with non-local means filer, generating a random centre surround operator to yield saliency map and enhancing the saliency with the Retinex theory. The effectiveness of this method is demonstrated by simplification and registration. Experimental results demonstrate that the proposed approach has achieved competitive results.
