This is a Dutch street, therefore it has many bikes in it: http://i.imgur.com/qQwAS.jpg http://i.imgur.com/qQwAS.jpg . Your application detects none of them...

This is a Dutch street, therefore it has many bikes in it: http://i.imgur.com/qQwAS.jpg http://i.imgur.com/qQwAS.jpg . Your application detects none of them... Is it because my ancient phone camera's pics are too grainy? Or do the bikes need to be en profile to be detected properly? Or maybe it's trained to detect bikes with people on them, instead of bikes parked in the street?
