The App has a simple UI to choose from the different cascades to evaluate. Since the amount of processing power required to evaluate one cascade and draw the found traffic sign takes some time you have to chose which one to actually evaluate.
- The Speed Meter Button launches a new Activity in which the current Speed in [m/s] is measured based on GPS Location data.
- With the Open Camera Button Camera launches in a new Activity and the elected cascade starts evaluating the frames.
This is what the app looks like when running
Here are some useful scripts to keep everything nice and clean. The finished Cascades and the Positive and Negative samples used for the classifiers
In this folder you will find all the necessary tools to create your own classifiers.
