Are the models pre-trained? #3

Hi, I'm a student who is interested in ball tracking solutions. I was impressed with your methods and results, so I decided to try out the code on my own. But I got poor results on the ISSIA dataset video (5th one), it rarely detected the ball. Aren't the models pre-trained with the ISSIA dataset? Or is there anything else I'm missing?

Also, if I want to apply the model to a video with a different ball size, would changing the bg_kernel value help? It would be appreciated if you can give me some suggestions.

Thanks in advance!

Hey, yeah, it is trained with ISSIA, but I've scaled the images down to 272 by 480 to make the training time reasonable and I think that really hurts. Sequence 5 is not accurately detected, lowering the threshold to 0.9999 alleviates the problem a bit, but it's still not great tbf.

Yeah, changing the bg_kernel should help, by making the cells bigger.
