Image Processing: What are occlusions?

Question

I\'m developing an image processing project and I come across the word occlusion in many scientific papers, what do occlusions mean in the context of i

Answer 1

Occlusion is the one which blocks our view. In the image shown here, we can easily see the people in the front row. But the second row is partly visible and third row is much less visible. Here, we say that second row is partly occluded by first row, and third row is occluded by first and second rows. We can see such occlusions in class rooms (students sitting in rows), traffic junctions (vehicles waiting for signal), forests (trees and plants), etc., when there are a lot of objects.
