edge
Description
This is an edge detector node. It takes an image and performs Canny edge detection, currently with fixed thresholds. It does not take account of ROIs, since this would be pointless when we're converting from a potentially multispectral image to greyscale (well, boolean). Exercise for the reader - add variable thresholds, either as numeric inputs or as numeric parameters settable from the node tab.
DQ bits of the bands in the source are combined together for the single
band of the result. Uncertainty is discarded.
