A Multiscale Metric for 3D Mesh Visual Quality Assessment
Many processing operations are nowadays applied on 3D meshes like compression, watermarking, remeshing and so forth; these processes are mostly driven and/or evaluated using simple distortion measures like the Hausdorff distance and the root mean square error, however these measures do not correlate with the human visual perception while the visual quality of the processed meshes is a crucial i...
متن کامل3d Mesh Refinement Procedure Using the Bisection and Rivara Algorithms with Mesh Quality Assessment
Mesh refinement procedures for the solution of three dimensional problems are described. The computational domain is represented by an assembly of tetrahedral elements and the mesh refinement is acheived by the bisection and Rivara methods using an explicit mesh density function coupled with an automatic 3D mesh generator. A couple of benchmark examples is used to compare the performance of bot...
متن کامل3D Video Quality Assessment
A key factor in designing 3D systems is to understand how different visual cues and distortions affect the perceptual quality of 3D video. The ultimate way to assess video quality is through subjective tests. However, subjective evaluation is time consuming, expensive, and in most cases not even possible. An alternative solution is objective quality metrics, which attempt to model the Human Vis...
متن کاملA Non-blind Robust Watermarking Approach for 3d Mesh Models
This paper presents non-blind and robust watermarking approach for three-dimensional (3D) mesh models using K-means clustering technique. K-means clustering technique is used to cluster 3D mesh vertices into suitable or non-suitable watermark carrier based on feature vector. Then the watermark is inserted in the selected vertices for being carrier watermark that come out from K-means clustering...
متن کاملBlind 3D Mesh Watermarking Based on Sphere-Shape Template
In this paper, we propose a novel blind 3D mesh watermarking scheme based on synchronization using a template. The proposed template has a sphere shape with a basis point and scale information for the watermarking. The template is invariant to translation, rotation, and scale. In the extraction process of the template, the post-processing, which sorts out the genuine template vertices from many...
