canny

Perform canny filtering on an image to expose edges.

Slice!(Contiguous, [2], V*) canny(Slice!(kind, [2], T*) slice, T lowThresh, T upThresh, EdgeKernel edgeKernelType = EdgeKernel.SOBEL, Slice!(Contiguous, [2], V*) prealloc = emptySlice!([2], V), TaskPool pool = taskPool)

Parameters

slice: Type: Slice!(kind, [2], T*)
Input image slice.
lowThresh: Type: T
lower threshold value after non-maxima suppression.
upThresh: Type: T
upper threshold value after non-maxima suppression.
edgeKernelType: Type: EdgeKernel
Type of edge kernel used to calculate image gradients.
prealloc: Type: Slice!(Contiguous, [2], V*)
Optional pre-allocated buffer.
pool: Type: TaskPool
TaskPool instance used parallelise the algorithm.
