Object Tracking Options (Get Set Shape Adapted Options) (G Dataflow)
Specifies the options to use for shape adapted object tracking.
tracking session in
Reference to the object tracking session.
options in
Behavior of the shape adapted algorithm.
Number of Histogram Bins
Number of bins per band to use for the object description.
Default: 8
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%
Max Scale Change
Maximum acceptable scale change. Values range from 0% to 100%.
Max Rotation Change
Maximum acceptable rotation change. Values range from 0 degrees to 180 degrees.
Max Shape Change
Maximum acceptable shape change. Values range from 0% to 100%.
Maximum Iterations
Maximum number of iterations the mean shift tracking process is repeated until convergence on the new location of the object.
Default: 15
get/set?
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.
Default: No error
tracking session out
Reference to the object tracking session.
options out
Options for the shape adapted algorithm.
Number of Histogram Bins
Number of bins per band to use for the object description.
Blending Parameter
Ratio that the algorithm uses.
Max Scale Change
Maximum acceptable scale change.
Max Rotation Change
Maximum acceptable rotation change.
Max Shape Change
Maximum acceptable shape change.
Maximum Iterations
Maximum number of iterations the mean shift tracking process is repeated.
error out
Error information.
The node produces this output according to standard error behavior.
