MAPLE_BOUNDARY, a MATLAB library which takes an image of a maple leaf and determines the pixels that form the boundary.
For a discussion of quasirandom sampling, Brian Hayes published a picture of a maple leaf and considered how its area could be estimated using a regular grid of points, random sampling, or quasirandom sampling.
For various reasons, it will be interesting to have a copy of this maple leaf image accessible. The MAPLE_BOUNDARY functions use various MATLAB procedures to turn the maple leaf image into a polygonal curve definining the boundary, following which various calculations may be made.

MAPLE_BOUNDARY is available in a MATLAB version.
CONVEX_HULL, a MATLAB program which demonstrates the computation of the convex hull of a set of 2D points.
FLORIDA_CVT_GEO, MATLAB programs which explore the creation of a centroidal Voronoi Tessellation (CVT) of the state of Florida, based solely on geometric considerations.
FLORIDA_CVT_POP, MATLAB programs which explore the creation of a centroidal Voronoi Tessellation (CVT) of the state of Florida, based on population density.
HAND_AREA, a MATLAB program which estimates the area of a curve which outlines a person's hand.
HAND_DATA, MATLAB programs which carry out some numerical exercises based on data that came from tracing several points on a person's hand.
MAPLE_AREA, a MATLAB library which takes the list of pixels that form the boundary of the image of a maple leaf within a picture, and uses grid, Monte Carlo, and Quasi Monte Carlo sampling to estimate the area of the leaf.
MESH2D_HAND, a MATLAB program which reads in a set of 59 points which outline a human hand, and calls MESH2D, which is able to create a fine triangular mesh of the region outlined by the points.
POLYGON, a dataset directory which contains examples of polygons.
TRIANGULATE, a MATLAB program which triangulates a polygonal region.
