In this paper we develop a theory for characterizing how deformable a shape is given a sequence of its observations. We define a term called ‘‘deformability index’’ (DI) for shapes. The novelty of the proposed method lies in its ability to separate the effects of observation noise from the underlying non-rigid deformation process. The DI is computed from the tracked positions of a sequence of d...

assessment of cardiac right‑ventricle functions plays an essential role in diagnosis of arrhythmogenic right ventricular dysplasia (arvd). among clinical tests, cardiac magnetic resonance imaging (mri) is now becoming the most valid imaging technique to diagnose arvd. fatty infiltration of the right ventricular free wall can be visible on cardiac mri. finding right‑ventricle functional paramete...

The shoreline development index—The ratio of a lake’s shore length to the circumference circle with area—Is core metric lake morphometry used in Earth and planetary sciences. In this paper, we demonstrate that index is scale-dependent cannot be compare lakes different areas. We show large will have higher measurements than smaller same characteristic shape, even when mapped at scale. Specifical...

Then the pixel shape index method is used to extract features of high spatial resolution remote sensing images and supplement spectral features.The experimental results show that feature can effectively distinguish ground objects with similar but different geometric shapes, superior classification in accuracy.Compared small ripple multi-scale region method, also achieves better results.On other...
