Example 1: WebCam access with OpenCV
Example 1: WebCam access with OpenCV
Introduction
In this example, we are using the PythonImage module and access your WebCam to show the video in a View2D.
Steps to do
Creating the network to be used for testing
Add the modules to your workspace and connect them as seen below.
The viewer is empty because the image needs to be set via Python scripting.
Example 2: Face Detection with OpenCV
Example 2: Face Detection with OpenCV
Introduction
This example uses the OpenCV WebCam Python script and adds a basic face detection.
Info:
The Python code used in this example has been taken from Towards Data Science.
Steps to do
Open Example 1
Add the macro module developed in Example 1 to your workspace.
