Idealy we would like to move to a content-based image retrieval system where we would be able to search based on certain features that can be derived from the image itself (color, shape, texture for example) so we could fine tune our results.
Yes, the presented example is a curious case, if we take the first three icons there and compare them based on share and color we can see that their shape is identical but the background is different. Based on this, should we consider different or identical? You can't have too many variations on a simple shape like a checkmark or a facebook logo so what variations should you allow and which ones would you consider as copying previous work?
