Canny Edge

Edge detection in grayscale images using Canny from scikit-image.
The resulting edge image is a binary image with edges in white.
Requires Python 3 environment with:
- Scikit-Image (tested with v 0.15 at time of development)

HoughCircle

Detect circles in grayscale images using the Hough Circle transform from scikit-image.
The circle detection works both on a initial grayscale images or after edge detection with Sobel or Canny.
It is an iterative search that test successive values of radius at all possible places in the image.
The larger the radius search range and the smaller the step size, the longer is the computation.
Requires Python3 environement with :
- Numpy
- Scikit-Image (0.15 at time of development)

This workflows uses a Python (Legacy) preference with a Python 3.6 environment and scikit-image 0.17. This is due to the components employing legacy Python script nodes.
