Decimate 2D contours/polygons
Have you ever worked with 2D boundary shape representations and noticed that the same shape can be represented with reasonable accuracy by a much smaller number of points? Did you ever need to reduce the complexity of a 2D shape while retaining as many salient features as possible? If so then DecimatePoly.m is the function you have been looking for.
Quick Demos
DecimatePoly_demo1: Simplify a 2D contour extracted from a binary image. Three binary images are included as examples. This demo requires Image Processing Toolbox to run.
DecimatePoly_demo2: Simplifying complex shapes while retaining geometrically and visually salient features.
DecimatePoly_demo3: Use DecimatePoly.m to improve the run-time of in-polygon tests at the cost of minor misclassification errors.
