Web数学における凸包（とつほう、英: convex hull ）または凸包絡（とつほうらく、英: convex envelope ）は、与えられた集合を含む最小の凸集合である。 例えば X がユークリッド平面内の有界な点集合のとき、その凸包は直観的には X を輪ゴムで囲んだときに輪ゴムが作る図形として視認することが ... WebThis standardization process is called as ‘continuum removal’ or ‘convex-hull’ transformation. It allows comparison of spectra that are recorded by different sensors under different lighting conditions. The technique of making a continuum or hull is similar to fitting a rubber band over the spectrum ( Fig. 14.11 ).

WebThere's some annoyance involved with generating contacts when a cylinder cap needs contacts inside of a convex hull face, but otherwise it's pretty similar to polygon clipping. Once the contact candidates have been collected for both inner contacts and edge intersections, they're reduced into a manifold of no more than 4 contacts. ... georgetown university act codeWebclass scipy.spatial.ConvexHull(points, incremental=False, qhull_options=None) # Convex hulls in N dimensions.
