Last Modified: June 25, 2019

Specifies the options to use for mean shift object tracking.

connector_pane_image
datatype_icon

tracking session in

Reference to the object tracking session.

datatype_icon

options in

Options for mean shift object tracking.

datatype_icon

Number of Histogram Bins

Number of bins per band to use for the object description.

Default: 8

datatype_icon

Blending Parameter

Ratio that the algorithm blends the current frame with the previous frame to track an object. Values range from 0% to 100%. 100% results in the algorithm inspecting the current frame only. 0% results in the algorithm inspecting the previous frame only.

Default: 10%

datatype_icon

Maximum Iterations

Maximum number of iterations the mean shift tracking process is repeated until convergence on the new location of the object.

Default: 15

datatype_icon

get/set?

Boolean input that specifies whether the node gets or sets the property value.

True Sets the property value.
False Gets the property value.

Default: True

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

tracking session out

Reference to the object tracking session.

datatype_icon

options out

Options for mean shift object tracking.

datatype_icon

Number of Histogram Bins

Number of bins per band to use for the object description.

datatype_icon

Blending Parameter

Ratio that the algorithm uses.

datatype_icon

Maximum Iterations

Maximum number of iterations the mean shift tracking process is repeated.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.

Where This Node Can Run:

Desktop OS: Windows

FPGA: Not supported

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