WebedgeThreshold: The threshold used to filter out edge-like features. Note that the its meaning is different from the contrastThreshold, i.e. the larger the edgeThreshold, the less features are filtered out (more features are retained). System.Double: sigma: The sigma of the Gaussian applied to the input image at the octave #0. http://shimat.github.io/opencvsharp/api/OpenCvSharp.Features2D.SIFT.html
