Course Description
How can you identify and locate objects in an image or video frame? How can you describe their shape characteristics and match these objects? OpenCV provides methods for several techniques that can be used separately or together to detect objects by their shapes, color ranges, and contour measurements. Learning how to detect objects of interest in images and video frames is an essential skill in many advanced computer vision and machine learning projects. The topics discussed in these lessons will provide a foundation for future work in computational image enhancement or computer vision AI applications.
In these lessons, you will learn how to detect objects in images and video frames using OpenCV. We will explore binary and grayscale thresholding techniques, edge detection, and contour analysis. By the end of these lessons, you will be able to build a skin detector and describe the objects detected in an image.
What You'll Learn
- Detect objects in images and video frames using OpenCV by their shapes, color ranges, and contour measurements
- Apply binary and grayscale thresholding techniques, including threshold types and adaptive thresholding, for object detection
