Class ContourEdgeIntensity<T extends ImageGray<T>>

java.lang.Object

boofcv.alg.shapes.polygon.ContourEdgeIntensity<T>

public class ContourEdgeIntensity<T extends ImageGray<T>>
extends java.lang.Object

Computes the average value of points sampled outside and inside the contour at regular intervals. At each sample location along the contour the local slope is computed using another contour point. This is then used to compute the tangent. Then points inside and outside along the tangent are sampled using bilinear interpolation. The value of these points are summed up and the average computed.
