ShapeAnalyzer
Shape Analysis Library, no third part library, pure in python.
Tools
- basic shapes: Point, LineSegment, Line, Circle, Rectangle, LineString, Polygon
- bounding geometry: envelope, convex hull, minimum area enclosing circle, minimum width enclosing rectangle
- shape descriptors: area, perimeter, roundness, curvature, circularity
Examples
a testing examples in test.ipynb. go to the directory and jupytor notebook. You need jupytor and numpy to run examples

Shape Descriptors
from shapeanalyzer.descriptors import ShapeDescriptor
import json
SD = ShapeDescriptor(Polygon(hull))
print json.dumps(SD.Descriptors(), indent=2){
