Quality Control of Manufactured Surfaces
2010Recent literature on statistical process monitoring pointed out that the quality of products and processes can be often related to profiles, where the function relating a response to one or more location variables (in time or space) is the quality characteristic of interest.

Quality Improvement of Surface Triangulations
2006This paper presents a new procedure to improve the quality of triangular meshes defined on surfaces. The improvement is obtained by an iterative process in which each node of the mesh is moved to a new position that minimizes certain objective function.

3D surface models are often stored as indexed face sets, whereas algorithms can typically treat only a subset of the so-representable surfaces. Besides this gap between "potential" input and "allowed" input, more and more algorithms specify their input requirements at a high level of abstraction (e.g.

Objective assessment of the surface quality of coated surfaces
Insight - Non-Destructive Testing and Condition Monitoring, 2011A novel procedure has been developed for the assessment of the surface finish of in-mould gel-coated fibre-reinforced polymer matrix composites. The technique involves photographing the reflection from a coated surface on an opaque screen and analysing the image using fractal dimensions.

Visual inspection of weld surface quality
Journal of Intelligent & Fuzzy Systems, 2020Welding is an important method for modern material processing. In actual processing, due to the influence of processing accuracy and welding thermal deformation, various defects often appear in the appearance of the weld. At present, visual inspection is mainly used for the appearance inspection of welds. The detection of weld defects mainly depends on

High Quality Triangulation of Implicit Surfaces
Ninth International Conference on Computer Aided Design and Computer Graphics (CAD-CG'05), 2006We present a new high quality tessellation method for implicit surfaces in this paper. The approach can handle arbitrary implicit functions and dynamic implicit surfaces based on skeletal primitives. We first samples the implicit surface uniformly using particle fission and floating, then reconstructs a triangular mesh from the sample points using ball

Image statistics and the perception of surface qualities
Nature, 2007The world is full of surfaces, and by looking at them we can judge their material qualities. Properties such as colour or glossiness can help us decide whether a pancake is cooked, or a patch of pavement is icy. Most studies of surface appearance have emphasized textureless matte surfaces, but real-world surfaces, which may have gloss and complex ...

Spectroscopic Evaluation of the Surface Quality of Apple
Journal of Agricultural and Food Chemistry, 2003Different spectroscopic techniques based on infrared and Raman were used to evaluate the natural wax and related surface quality of apple fruit. Transmission near-infrared (NIR) spectroscopy was applied to solutions of single wax components and extracted apple wax. Fourier transform infrared (FTIR) spectroscopy was used for transmission measurements of

Surface quality assessment of subdivision surfaces on programmable graphics hardware
Proceedings Shape Modeling Applications, 2004., 2004We propose a method of subdivision surface quality assessment by reflection lines on programmable graphics hardware (GPU). Using reflection lines is effective for surface quality assessment because the shapes of these lines are changed according to a slight variance of surface shapes.

Surface roughening, surface melting and crystal quality
Faraday Discussions, 1993The modelling of crystal surfaces, both in equilibrium and during growth, is now at a stage where the relation between surface structure and crystal quality are accessible for future studies. The classical point of view is that the roughening transition marks the transition from step growth to rough growth with qualitative changes in the growth rate ...
