✨ Use the command-line interface
✨ Load and display images

Image Basics


✨Image coordinate system in OpenCV
✨Use array slicing to grab regions of an image



✨Use OpenCV to draw shapes and objects
✨Create polygons and meshes

Image Arithmetic


✨Learn math operations on images
✨Perform bitwise operations for filtering

Gradients & Edge Detection


✨Learn about Sobel and Scharr operators
✨Understand image gradients

Incoming rant:
Today I answered 163 blog post comments and 283 emails on computer vision and deep learning. All for free. It took me 10 hours. I love helping and teaching others. If I didn’t, I would do it. But there exists a small minority of readers that hurt me/drain me.
They take advantage of free help — and what’s worse, I don’t think they are aware of the behavior. They make assumptions of your time, that if they email you, they are automatically *owed* or *deserve* a response, just by virtue of sending you a message.
Others will email in 15+ times in a single month and expect a response each time. Others write essays of emails, taking advantage of your time and not being respectful. Others don’t want to actually *learn*, they just want “done for them” code for their project or report.
