MAPLE_AREA
Estimate the Area of a Maple Leaf from an Image


MAPLE_AREA, a MATLAB library which uses several approaches to estimate the area of a maple leaf using an image.

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.

The MAPLE_BOUNDARY functions used various MATLAB procedures to turn the maple leaf image into a polygonal curve definining the boundary. The functions in MAPLE_AREA use various sampling techniques to estimate the area of the maple leaf.
