* with walking poles - STILL UNSURE if it's possible to detect
* handicap (with wheelchair)
* car
* bus
* cyclist
## How?
* I'm still debating if I should use `YOLO` or `SSD` for the run.
## Challenge?
Object tracking algorithm from both `opencv` and `dlib` are pretty much the same. Good tracking capability, but they would lose track when there is a building or even a small pillar blocking the sight. Thus, we need to detect them all separately on each zone and find a way to link "object" that comes to the __blocking zone__ and get through it the other way. I guess this should be able to get all the trace we need and connecting them all together. Yes, when there are tons of objects overlapping, things would get much tougher. But that is the issue for the other day.
