OpenCV Python Tutorials

OpenCV is a computer vision library that is available in Python. The OpenCV library is mostly used for image processing. It is open-source and cross-platform compatible. I highly recommend you get the “Computer Vision: Models, Learning, and Inference Book” to learn Computer Vision. We can use OpenCV to process images and videos and can build real-time computer vision applications. This OpenCV Python guide will help you to learn OpenCV in a very short time. You can perform so many tasks using OpenCV, such as:

• Face Detection and Recognition
• Capture, Process, and Save Videos
• Hand Gesture Recognition
• Detect Defective Products in Manufacturing
• Factory Automation (Visual Inspection, Vision Guided Robotics)
• Optical Character Recognition (OCR)
• Vehicle Detection and Counting with their speed
• Iris Recognition (Biometrics)
• Automatic Tagging of Images
• Medical Image Analysis
• Object Detection and Tracking
• Landmark Recognition
• Geometric Transformations of Images
• Panorama Image Stitching
• Surveillance
• Animal Monitoring
• Background Removal
• Feature Detection
• Handwriting Recognition
• Agriculture (Soil Conditions, Yield Estimation)
• People Counter (People Monitoring)
