What's the definition of occluded?

[davidwagner]

I'm wondering what counts as 'occluded'. Are these images of bicycles occluded?

train/bicycle/08495fcbbb5651d7.jpg - is it occluded by the light pole in front?

train/bicycle/60d1dbbc4fb92378.jpg - is it occluded by the rider's right leg and/or right arm?

Is a bicycle with a rider on it almost always going to be considered occluded?

Okay yes, this is a case I don't think we thought carefully enough about. There are some other images that are like this (e.g., birds in cages or behind a fence). I think it's probably a clearer task to disallow these images (otherwise: how much occlusion is okay? is a fence? a poll? a fire hydrant? at some point it's too much), but as you say that makes especially the bicycle class with a person it it difficult...

Do you have any thoughts?
