Calculates the zones of influence between particles, starting from a labeled image.

Each labeled particle is dilated until the particles reach neighboring particles, at which time this growth is stopped. The source image must have a border greater than or equal to 1. 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. Use the Label node to label the image prior to using Segmentation.

image src

Reference to the source image.

datatype_icon

image dst

Reference to the destination image.

datatype_icon

error in

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.

error in does not contain an error error in contains an error
If no error occurred before the node runs, the node begins execution normally.

If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error

datatype_icon

image dst out

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.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.

Desktop OS: Windows

FPGA: Not supported

Web Server: Not supported in VIs that run in a web application
