Beam as structure element #22

Closed e-koch closed 9 years ago

e-koch commented 9 years ago

Implements an EllipticalTophat2DKernel, allowing for the beam to be converted into a structure element for morphological operations. This required implementing an EllipticalDisk2D model as well.

@keflavich - The tophat area should now match the gaussian. I'm going to do a bit more testing tomorrow though.

@e-koch ok just ping me when you want it merged

e-koch commented 9 years ago

@keflavich - Good to merge!

Example of a beam and the elliptical gaussian (image) with the elliptical tophat (contour).

Octagonal ellipses are my favorite ellipses.
