A Curvature Tensor Distance for Mesh Visual Quality Assessment
Résumé
This paper presents a new objective metric for assessing the visual difference between a reference or 'perfect' mesh and its distorted version. The proposed metric is based on the measurement of a distance between curvature tensors of the two triangle meshes under comparison. Unlike existing methods, our algorithm uses not only eigenvalues but also eigenvectors of the curvature tensor to derive a perceptually-oriented distance. The metric also accounts for some important properties of the human visual system. Experimental results show good coherence between the proposed objective metric and the subjective assessment.
