Classifies the contour located in the given image.

connector_pane_image
datatype_icon

contour image in

Reference to the image containing a contour.

datatype_icon

kernel width

Size of the kernel used to compute the curvature profile of the selected contour.

datatype_icon

curvature classes

Array with one element for every curvature class in the image.

datatype_icon

minimum curvature

Minimum curvature for the selected curvature range.

datatype_icon

maximum curvature

Maximum curvature for the selected curvature range.

datatype_icon

class label

Class to which the sample belongs.

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

contour image out

Reference to the image containing a contour.

datatype_icon

classified curves

An array that specifies information about the curves.

datatype_icon

length (pixel)

Length, in pixels, of the curves within the curvature range.

datatype_icon

length (real)

Length, in calibrated units, of the curves within the curvature range.

datatype_icon

maximum curvature (pixel)

Maximum curvature, in pixels, for the selected curvature range.

datatype_icon

maximum curvature (real)

Maximum curvature, in calibrated units, for the selected curvature range.

datatype_icon

class label

Class to which the the sample belongs.

datatype_icon

curve points

Point-coordinate cluster that defines the points of the curve.

datatype_icon

x

X-coordinate of the point.

datatype_icon

y

Y-coordinate of the point.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.
