  • However, the spatial occlusion technique has been used in only a few studies because of editing difficulties.

  • Most students need to repeat this experience; after enough of these experiences of intermittent occlusion, they start to notice and use their canes to detect curbs with confidence and without further prompting.

    Academic text (2010)
  • In computer graphics, occlusion can occur when one object blocks the view of another, affecting rendering quality.

Morphology

occlusion = occlude (semi-transparent) = occlude + sion

The computer-vision/graphics sense reflects the general meaning 'to hide/block from view', but it is a technical application of the verb and used in specialized contexts.

Etymology

Occlusion comes from the Latin occludere and its parts ob- 'against' and claudere 'to close', so imagine one object 'closing' the view of another. That's why in graphics and vision occlusion means one thing hiding or blocking another from the camera.
