AIDetectContour (Function)

In french: IADétecteContour

Detects the contours of the shapes in an image.

Example

monContour is aiConfigureContourDetection
monContour.DetectionAlgorithm = aiDetectContourCannyEdge
monContour.Dilate = True
monContour.GaussianFilterKernelSize = 3
monContour.ValueThreshold = 150
monContour.ValueThresholdMax = 255

monPolygone is Polygon
monPolygone = AIDetectContour("Image_test_contour_3.png", monContour)

Syntax

<Result> = AIDetectContour(<Image> [, <Parameters>])

<Result>: Array of Polygons

Array of Polygon variables containing the different contours detected.

<Image>: Character string

Image to be analyzed. The image can correspond to:
a variable of type Image,
the name and path of the image,
the name and path of a PDF file,
an Image memo item,
an Image control.

<Parameters>: Optional aiConfigureContourDetection variable

Name of the aiConfigureContourDetection variable used to set the contour detection options. If this parameter is not specified, the default options are:
Edge detection algorithm developed by J.F.Canny in 1986
Dilation: False
Gaussian filter size: 3
Threshold value: Default value: 150.0
Maximum threshold value: Default value: 255.0

Remarks

Results can vary greatly depending on the parameters specified with the aiConfigureContourDetection variable.
The detection process is powered by artificial intelligence, and does not guarantee total accuracy.
