Computer vision and insect vision – compared

If you have been experimenting with the widely used OpenCV project, you may have found the StereoSGBM functionality that tries to find the difference between two images to find depth!

In a WIRED video here, they do a similar experiment to see how exactly this works in praying mantids. Interesting! They theorize that they use motion rather than actually seeing depth in a picture based on experiments.

And if you are at Humboldt Math Festival this coming weekend you can take a look at that OpenCV library used for stereovision and some other random and interesting mathematical demos! It’s not just for kids! 🙂
