Reading #15: Image-Based Trainable Symbol Recognizer

Comments on:

  • None yet

Summary:

Kara and Stahovich present a vision-based trainable symbol recognizer. The recognizer is scale, translation, and rotation invariant, and runs very quickly. The system is an instance-based classifier, so it is easy to add new classes or new training instances of already-defined classes.

Discussion:

This paper presents a good symbol recognizer that's pretty easy to implement. It's also a good introduction to a number of interesting distance metrics.
