SAGA.grid_filter.16: Wombling (Edge Detection)

Continuous Wombling for edge detection. Uses magnitude of gradient to detect edges between adjacent cells. Edge segments connect such edges, when the difference of their gradient directions is below given threshold.

Inputs

Minimum magnitude as percentile.

number

Maximum angular difference as degree between adjacent segment points.

number

Minimum number of neighbouring potential edge cells with similar direction.

integer

Alignment

string

Edge Connectivity

string
