Are pixels enough to make a recognizable image?

If we are asked to identify who is in the picture, then the 150 x 100 pixel image should be good enough. The background is redundant to the face recognition but certainly helpful in this case. Recent studies [5] show that lower resolutions of images actually are better for computer vision!

What is the difference between detection and identification?

Detection: ability to distinguish an object from the background. Recognition: ability to classify the object class (animal, human, vehicle, boat …) Identification: ability to describe the object in details (a man with a hat, a deer, a Jeep …)

How can facial recognition be improved?

This is a significant increase because even experienced face identification staff can get as many as one in two wrong when it comes to comparing photos with unfamiliar faces.

Which is better 720p or 1080p camera?
