Shape Match Tool (G Dataflow)

Reference to the source image.

Reference to the 8-bit binary template to search.

Reference to any binary image that contains the objects from image src that match the object in the image template.

Boolean value that specifies whether to use size or scale invariance when matching objects in the source image to the template object.

Default: TRUE

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

Maximum allowed deviation between the template shape and similar shapes in the image.

Valid values are between 0 and 1.

Boolean value that specifies the mode of connectivity used by the algorithm for particle detection.

The connectivity mode directly determines whether an adjacent pixel belongs to the same particle or a different particle.

Default: 8

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.

Array of clusters in which each cluster contains information on the matched objects.

Global Rectangle

Bounding rectangle of the object.

x1Left

X-coordinate of the top-left corner of the rectangle.

y1Top

Y-coordinate of the top-left corner of the rectangle.

x2Right

X-coordinate of the bottom-right corner of the rectangle.

y2Bottom

Y-coordinate of the bottom-right corner of the rectangle.

Centroid

Point-coordinate cluster containing the location of the centroid of the object.

Object Size

Size, in pixels, of the object.

Score

Output, between 1 and 1000, that specifies how similar the object in the image is to the template.

A score of 1000 implies a perfect match.

Number of template matches found in the inspection image based on the input settings.

Error information.

The node produces this output according to standard error behavior.
