It utilizes either a predefined kernel type (circle, square, etc.) or a user-defined kernel. Key actions include specifying the kernel's radius, type, units (pixels or meters), and iterations. The function can also utilize a custom kernel, in which case the kernel type and radius are disregarded. The output is an image with the filter applied.\n"]]
