Partitioning of convex polygon
Web1 Jun 2015 · Compared with existing superpixel methods, our method can partition an image into fully convex and compact superpixels with better boundary adherence. Web24 Nov 2024 · This can be approached in two ways : i) by partitioning the given polygon into convex polygons such that there is no overlap between the convex polygons ii) by covering the given polygon using convex polygons such that their union gives the original polygon. In this case there can be overlap between the convex polygons

Web1 Jun 2015 · Consequently, output polygons are often imprecise, typically with edges that do not fit accurately the object silhouettes. Recent works on the partitioning of images into polygonal cells [AS17 ... Polygon partitioning is an important class of problems in computational geometry. There are many different polygon partition problems, depending on the type of polygon being partitioned and on the types of units allowed in the partition. The term polygon decomposition is often used as a general term that … See more In geometry, a partition of a polygon is a set of primitive units (e.g. squares), which do not overlap and whose union equals the polygon. A polygon partition problem is a problem of finding a partition which is minimal in some … See more The same two variants of the problem were studied for the case in which the pieces should be pseudotriangles – polygons that like triangles have exactly three convex … See more A special sub-family of polygon partition problems arises when the large polygon is a rectilinear polygon (also called: orthogonal polygon). … See more A quadrilateralization or a quadrangulation is a partition into quadrilaterals. A recurring characteristic of quadrangulation problems is whether they Steiner point are allowed, i.e., whether the algorithm is allowed to add points which are not vertices of … See more Polygon decomposition is applied in several areas: • Pattern recognition techniques extract information from an object in order to describe, identify or … See more The most well-studied polygon partition problem is partitioning to a smallest number of triangles, also called triangulation. For a hole-free polygon with $${\displaystyle n}$$ vertices, a triangulation can be calculated in time A related problem is … See more In VLSI artwork processing systems, it is often required to partition a polygonal region into the minimum number of trapezoids, with two horizontal sides. A triangle with a horizontal side is considered to be a trapezoid with two horizontal sides one … See more
WebPartitions of polygons into components that satisfy various shape criteria have been the focus of considerable research. Algorithms have been developed [Kei85] that produce partitions of simple polygons into the fewest convex polygons, spiral polygons, star-shaped polygons, or monotone polygons, when all the vertices of WebDiscussion: Polygon partitioning is an important preprocessing step for many geometric algorithms, because geometric problems tend to be simpler on convex objects than on nonconvex ones. It is often easier to work with a small number of convex pieces than with a single nonconvex polygon. Several flavors of polygon partitioning arise, depending ...
