morph: Morphological Operations
Description
morph applies various morphological operations (see Note)
to an Image object.
Usage
morph(image, operation, kernel = NULL, k_shape = "rectangle",
k_height = 5, k_width = 5, iterations = 1)
Arguments
operation
A string corresponding to the name of a morphological
operation to apply to the image (see Note).
kernel
A binary matrix. If the matrix is not binary, all positive values
will be automatically converted to 1, all negative values to 0, unless
operation = "hitmiss" in which case they will be converted to -1.
k_shape
A string corresponding to the shape of the kernel for the
morphological operation (see Note; default: "rectangle"). Ignored if a
custom kernel is provided.
k_height
The half-height in pixels of the kernel. Ignored if a custom
kernel is provided.
k_width
The half-width in pixels of the kernel. Ignored if a custom
kernel is provided.
iterations
The number of times the morphological operations should be
applied.
