Abstract: This is an introductory textbook for teachers, students, professionals, and hobbyists who want to learn the basics of computer vision. The book is completely based around the OpenCV library, ...

I am attempting to convert Canny edges to polylines so that I can use them in other geometry libraries (for example, Shapely). FindContours() does a good job of this when the lines from Canny produce ...

At first blush, it might seem like projects that make extensive use of computer vision or machine learning would need to be based on powerful computing platforms with plenty of clock cycles and memory ...

Image processing has become a part of our lives. Nobody is surprised by facial recognition or driving lane detection. Today, the most common library for these purposes is OpenCV. Currently, OpenCV is ...

Per the documentation, "Contours can be explained simply as a curve joining all the continuous points (along the boundary), having same color or intensity." This is not what is normally understood as ...

Here’s a tip from a wizened engineer I’ve heard several times. If you’re poking around a circuit that has failed, look at the resistor color codes. Sometimes, if a resistor overheats, the color code ...

Abstract: The purpose of this paper is to introduce and quickly make a reader familiar with OpenCV (Open Source Computer Vision) basics without having to go through the lengthy reference manuals and ...
