Detailed Description

The SimpleEdgeDetection Algorithm class houses the Edge Detection Algorithm.

This algorithm uses a picture of Earth and finds all points on the horizon within the picture by employing thresholding to identify "space", and then figure out the contour of "space" that is shared by Earth's edge, returning that as the result

Constructor & Destructor Documentation

SimpleEdgeDetectionAlgorithm()

found::SimpleEdgeDetectionAlgorithm::SimpleEdgeDetectionAlgorithm ( unsigned char  threshold, int  borderLength, decimal  offset  )

inline

Constructs a new SimpleEdgeDetectionAlgorithm.

Parameters

threshold	The threshold to use for detecting space
borderLength	The thickness of the image's borders
offset	The offset to apply to edge points

Member Function Documentation

Run()

Points found::SimpleEdgeDetectionAlgorithm::Run ( const Image &  image )

override

Provides an estimate of the edge points of Earth, as the shared edge between space and Earth.

Parameters

image

The image of Earth

Returns

The points on Earth's edge in image

Postcondition

The edge points returned are in polar order, i.e. if we define the centroid of the points as P, for any three consecutive points A B and C, angle APB is less than angle APC
