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

• Bounding Geometry

• Shape Descriptors

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