Cascade Classifier Training
Our team is looking to detect the FRC logo on the totes and I've run into more than a few problems with the training process.
I've done some work with pre-made datasets, but making my own has proved to be a challenge. Has any team had any luck with cascade classifier training or is there a better way to find the FIRST logo? If anyone has had luck, how many positive samples did you use? How many negatives? How many stages? There are so many parameters to fiddle with and it would be nice to know if someone has been successful before. Thanks, Team 114

Re: Cascade Classifier Training
When you get a chance, could you please benchmark the algorithm for how long it take to identify the object? There isn't good literature on low sample sized classifying algorithms.

Re: Cascade Classifier Training
Using our NVIDIA Quadro K4000 to process the images, we get about 20 fps with our current configuration. Using just the i5, we get about 8.5.

Re: Cascade Classifier Training
Thank you so much. So it isn't too slow. When you have a lot of positive and negative image samples and what not, you sometimes see performances of about 5 fps on good machines.
