J = imbothat(I::Union{GMTimage{<:UInt8, 2}, GMTimage{<:Bool, 2}}; hsize=3, vsize=3)::GMTimage

keywords: GMT, Julia, image morphology, bothat

Do a morphological bop-hat operation on a grayscale or binary image.

Bottom-hat computes the morphological closing of the image and does a: closing - orig_image This transform isolates pixels that are darker than other pixels in their neighborhood.

Args

• I::Union{GMTimage{<:UInt8, 2}, GMTimage{<:Bool, 2}}: Input image.

Kwargs

• hsize::Int=3: Horizontal size of the 'box' structuring element.

• vsize::Int=3: Vertical size of the 'box' structuring element.

Returns

A new GMTimage of the same type as I with the bothat applied.
