Separates touching particles, particularly small isthmuses found between particles.
This node performs n erosions where n equals number of erosions and then reconstructs the final image based on the results of the erosion. If an existing isthmus is broken or removed during the erosion process, the particles are reconstructed without the isthmus. The reconstructed particles have the same size as the initial particles, except that they are separated. If no isthmus is broken during the erosion process, the particles are reconstructed as they were initially found and no change is made. The source image must be an 8-bit binary image and have a border greater than or equal to 1 pixel. This node modifies the source image. If you need the original source image, create a copy of the image using the Copy Image node before using this node.
Reference to the source image.
Reference to the destination image.
Number of erosions that are used to separate the particles.
Default: 1
Error conditions that occur before this node runs.
The node responds to this input according to standard error behavior.
Standard Error Behavior
Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.
Default: No error
2D array that contains the structuring element to apply to the image.
The size of the structuring element, or the size of this array, determines the processing size. A structuring element of 3 × 3 is used if this input is not connected.
Reference to the destination image.
If image dst is connected, image dst out is the same as image dst. Otherwise, image dst out refers to the image referenced by image src.
