I'm getting images from a C328R camera attached to a small arduino robot. I want the robot to drive towards orange ping-pong balls and pick them up. I'm using the C# code supplied by funkotron76 at http://www.codeproject.com/KB/recipes/C328R.aspx.

Is there a library I can use to do this, or do I need to iterate over every pixel in the image looking for orange? If so, what kind of tolerance would I need to compensate for various lighting conditions?

I could probably test to figure out these numbers, but I'm hoping someone out there knows the answers.

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
