Owning Palette: Machine Vision
Requires: NI Vision Development Module

Use the Contour Analysis VIs to extract contours from an image, fit contours with an equation, learn and compute contour data, and to classify contour data.

Palette Object Description
IMAQ Extract Contour

Extracts a single, best contour from an image. If the input image is calibrated, the contour will be learned with calibration.

IMAQ Fit Contour

Fits a contour with an equation. The fit will occur in corrected space if the contour is calibrated.

IMAQ Overlay Contour

Overlays a contour on an image.

IMAQ Get Contour Info

Returns all the information describing a contour.

IMAQ Compute Curvature

Computes the curvature profile along the contour.

IMAQ Classify Curvature

Classifies the contour located in the given image.

IMAQ Compute Contour Distances

Compares a target contour with a template contour, and calculates the distance between the contours.

IMAQ Classify Contour Distances

Classifies the distance between a image containing a contour and a template image containing a contour.

IMAQ Setup Learn Contour Pattern

Optimizes and fine-tunes advanced parameters used during the learning phase. Run this VI before the IMAQ Learn Contour Pattern VI.

IMAQ Learn Contour Pattern

Creates a description of the template image for which you want to search during the contour matching phase.

IMAQ Setup Match Contour Pattern

Sets parameters that are used during the matching process.

IMAQ Advanced Setup Match Contour Pattern

Optimizes and fine-tunes advanced parameters used during the contour matching phase.
