Canny¶
Applies Canny edge detection to an image.
According to Canny’s edge detection algorithm, the filter performs Gaussian smoothing, edge detection with a Sobel filter and then uses hysteresis thresholding and non maximum suppression to end up with a binary imnage of the edges.
You can follow this node with a Threshold node to convert the binary image to a region.
Inputs¶
Image (Type: Image)¶
The input image.
Sigma (Type: Double)¶
Determines the size of the Gaussian filter kernel.
SobelSize (Type: Int32)¶
Determines the size of the Sobel filter kernel.
Low (Type: Double)¶
The low threshold of the hysteresis thresholding expressed as a percentage.
High (Type: Double)¶
The hiegh threshold of the hysteresis thresholding expressed as a percentage.
