| f | Image [ Gray-scale (uint8 or uint16) image ] |
| g | Image
[ Gray-scale (uint8 or uint16) or binary image
]
marker image: binary or labeled. |
| Bc | Structuring Element
(watershed connectivity) Default: |
| LINEREG | String
Output image: 'LINES' or 'REGIONS'. Default: |
| Y | Image [ Gray-scale (uint8 or uint16) or binary image ] |
mmCwatershed creates the image y by detecting the domain of the catchment basins of f indicated by the marker image g, according to the connectivity defined by Bc. According to the flag LINEREG y will be a labeled image of the catchment basins domain or just a binary image that presents the watershed lines. To know more about watershed and watershed from markers, see [BM93]. The implementation of this function is based on [LF00].
WARNING: There is a common mistake related to the marker image g. If this image contains only zeros and ones, but it is not a binary image, the result will be an image with all ones. If the marker image is binary, you have to set this explicitly using the logical function.
