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.

Tracking objects of a specific color


In order to build a good object tracker, we need to understand what characteristics can be used to make our tracking robust and accurate. So, let's take a baby step in this direction, and see how we can use colorspaces to come up with a good visual tracker. One thing to keep in mind is that the color information is sensitive to lighting conditions. In real-world applications, you need to do some preprocessing to take care of this. But for now, let's assume that somebody else is doing this and we are getting clean color images.

There are many different colorspaces and picking up a good one will depend on what people use for different applications. While RGB is the native representation on the computer screen, it's not necessarily ideal for humans. When it comes to humans, we give names to colors that are based on their hue. This is why HSV (Hue Saturation Value) is probably one of the most informative colorspaces. It closely aligns with how we perceive...
