Mastering Monocular Cues: How One Eye Can Provide Depth and Distance Perception

Monocular Cues

provide depth information when viewing a scene with one eye •Partial Occlusion -ex: king of clubs blocking king of spades makes king of clubs look closer things that occlude other things are usually closer •Relative height -things look closer to you if they are higher or lower in the image, above or below horizon•Retinal size -when objects are known to be the same size we can use their size on the retina as a cue to depth -smaller being further away

Monocular cues are visual cues that we can perceive using only one eye. They provide depth and distance information about the world around us. There are several types of monocular cues:

1. Linear perspective: This monocular cue occurs when two lines that are parallel in the real world appear to converge in the distance. The closer the lines are to each other, the farther away they appear.

2. Texture gradient: This monocular cue occurs when the size and spacing of textures become smaller as they move away from the viewer. The closer the textures are, the larger they appear.

3. Interposition: This monocular cue occurs when one object appears to block another. The object in front is perceived as closer than the one behind.

4. Relative size: This monocular cue occurs when objects that are the same size appear to be different sizes because of their distance from the viewer. The larger the object, the closer it appears.

5. Height in the visual field: This monocular cue occurs when objects that are higher in the visual field are perceived as farther away than those that are lower.

6. Shadows: This monocular cue occurs when the direction and length of shadows give clues about the direction and distance of light sources and objects.

Overall, monocular cues help us perceive depth and distance in our environment with the use of only one eye.
