However, the resulting representation only describes the appearance of image patches as well as image noise, and lacks a semantic description of shapes — useful, e.g., for grasping, robotic control, planning.
In order to a shape descriptor be useful for shape similarity computation, some properties are usually required: invariance in translation, rotation, and scale, and that each element in this dataset could be indexed so that fast and effective retrieval and comparison may be applied.
To address this question, we reconstruct the slab at the surface to determine its original shape, which is useful for plate reconstructions.
It is suggested that the use of a fixed "whirling" constant K for all structural mode shapes of a tube array may be too restrictive for low frequency, long wavelength modes, whereas a "whirling" constant dependent on tube array mode shape is more useful for design purposes.
A spline function, defined by piecewise polynomials, has a flexible shape that is useful for adjusting for non-linear effects.
Reports have suggested that optic disc shape parameters are useful for classifying glaucomatous eyes, but are less useful compared to RNFL parameters.
A spline function, defined by piecewise polynomials, has a flexible shape that is useful for modelling unknown and potentially variable seasonal and long term patterns.
The ability to fabricate modules with different shapes may be useful for two reasons: (i) Encapsulating cells of different types in modules of different shapes or sizes allows discrimination by eye, gravity, or (in principle) velocity in a gentle flow.
For superposition modulation, the results showed that constellation shaping seems more useful for high values of M.
