Do I need to mark all objects in an image

A have images database with a lot of objects in the same class in an image, for example a lot of motorbikes. Do I need to mark all objects? If I mark only one object and use such kind of images to train. Does it affect to the model quality? Thanks!

Yes, you must.

The network will learn not to detect non-marked bikes.
DNN will distinguish marked and non-marked bikes(will look for features, what distinguishes a marked bike), and will only detect bikes that are similar to marked ones, and will not detect similar to unmarked ones.
Thank you very much! That why even I have 20k of images for an class but the quality of the model which I built is very low. I will try to improve!
