Class ExampleFitPolygon

java.lang.Object

boofcv.examples.features.ExampleFitPolygon

public class ExampleFitPolygon
extends java.lang.Object

Demonstration of how to convert a point sequence describing an objects outline/contour into a sequence of line segments. Useful when analysing shapes such as squares and triangles or when trying to simply the low level pixel output.

Method Detail

fitBinaryImage

public static void fitBinaryImage(GrayF32 input)

Fits polygons to found contours around binary blobs.

fitCannyEdges

public static void fitCannyEdges(GrayF32 input)

Fits a sequence of line-segments into a sequence of points found using the Canny edge detector. In this case the points are not connected in a loop. The canny detector produces a more complex tree and the fitted points can be a bit noisy compared to the others.

fitCannyBinary

public static void fitCannyBinary(GrayF32 input)

Detects contours inside the binary image generated by canny. Only the external contour is relevant. Often easier to deal with than working with Canny edges directly.

main

public static void main(java.lang.String[] args)
