op morph

Perform morphological operation. FireSight wrapper for:

• OpenCV erode
• OpenCV dilate
• OpenCV morphologyEx

Parameters:

• mop Default MORPH_OPEN. Also MORPH_CLOSE, MORPH_DILATE, MORPH_ERODE, MORPH_GRADIENT, MORPH_TOPHAT, MORPH_BLACKHAT
• ksize JSON [width,height] array or integer giving kernel size. Default 3
• shape Default MORPH_ELLIPSE. Also MORPH_RECT and MORPH_CROSS.
