Conditional random field-based mesh saliency

We propose a new method for detecting mesh saliency, a reflection of perception-based regional importance for 3D meshes. The basic idea is to incorporate the Conditional Random Field (CRF) framework with a saliency detection process. We first produce a multi-scale representation for a mesh. Then, a CRF is designed to robustly detect salient regions utilising neighbourhood consistency. By inferring the CRF via belief propagation algorithm, we actually make use of the global statistic information in the saliency detection process. Experimental results demonstrate the robustness and the effectiveness of the proposed method.
