With a zero-cross edge detection, in the help section, it says you can input your own filters and if you don't, it iwll default to a LoG filter. What inputs can I put in? I know all of the different edge detection methods, but with the Zero-cross method in particular, it asks for a user input for the filter to be used prior to the zero-crossing and I am trying to figure out what kind of filters I can input.
