Mesh saliency, which measures the perceptual importance of different regions on a mesh, benefits a wide range of applications. However, existing mesh saliency models are largely built with hard-coded formulae, which cannot capture true human perception. Some existing techniques utilise indirect measures to capture user perception (e.g., mouse clicks), which can be unreliable. In this work, we collect eye-tracking data for 3D objects seen from different views, and develop an optimisationbased approach to fusing heat-maps captured from individual views to form consistent saliency maps on meshes. To predict mesh saliency on a new shape, we further develop a learningbased approach that regresses local surface characteristics based on a set of input features. Experimental results show that our learning-based method achieves better performance than stateof-the-art methods for unseen shapes. We will make our dataset publicly available.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
