David Millán Escrivá
David Millán Escrivá was 8 years old when he wrote his first program on an 8086 PC in Basic, which enabled the 2D plotting of basic equations. In 2005, he finished his studies in IT with honors, through the Universitat Politécnica de Valencia, in human-computer interaction supported by computer vision with OpenCV (v0.96). He has worked with Blender, an open source, 3D software project, and on its first commercial movie, Plumiferos, as a computer graphics software developer. David has more than 10 years' experience in IT, with experience in computer vision, computer graphics, pattern recognition, and machine learning, working on different projects, and at different start-ups, and companies. He currently works as a researcher in computer vision.

Chapter 21. Avoiding Common Pitfalls in OpenCV

OpenCV has been around for more than 15 years now. It contains many implementations that are outdated or unoptimized and are relics of the past. An advanced OpenCV engineer should know how to avoid basic mistakes in navigating the OpenCV APIs, and see their project to algorithmic success.

In this chapter, we will review the historic development of OpenCV, and the gradual increase in the framework and algorithmic offering, alongside the development of computer vision at large. We will use this knowledge to see how to figure out whether a newer alternative exists within OpenCV for our algorithm of choice. Lastly, we will discuss how to identify and avoid common problems or sub-optimal choices while creating computer vision systems with OpenCV.

The following topics will be covered in this chapter:

  • A historic review of OpenCV and the latest wave of computer vision research
  • Checking the date at which an algorithm became available in OpenCV, and whether...
