Which monocular depth cue suggests that objects further away are obscured by those in the foreground?

Interposition, also known as occlusion, is a monocular depth cue that occurs when one object partially obscures another object. This cue allows us to perceive depth and distance based on the relative positioning of objects in our visual field. When an object is in front of another, our brains interpret that the obscured object is further away. Because our perception of depth is influenced by the arrangement of objects, interposition becomes a powerful indicator for assessing distances between them.

In contrast, the other concepts listed do not specifically pertain to the relationship of distance between overlapping objects. Floaters refer to small particles that float in our vision and are unrelated to depth perception. Convergence involves the inward movement of the eyes when focusing on a close object, which is a binocular cue rather than a monocular one. Figure-ground organization pertains to the visual system’s ability to distinguish an object (the figure) from its background, which does not provide insights about depth or spatial relationships.
