Depth Perception

Depth Perception is the ability to perceive the world in three dimensions and to be able to perceive depth and distance of an object. Depth Perception consists of many monocular cues such as relative size, relative clarity, and many more. In this picture we are able to see the depth of the picture due to our depth perception.

Reversible Figures

Reversible figures are ambiguous 2D drawings that can be seen as 3D drawings and can be seen as two different pictures, this creates two different perspectives. In this picture two different images can be seen, one is a picture of Wolverine and the other one is of two Batman faces, this shows a 3D images which is depicted as the Wolverine face and there is a 2D image which is the Batman faces

Phi phenomenon

Phi phenomenon is when two lights that are next to each other create the illusion of movement.  If they blink on and off in quick succession, it looks like a single light that is moving between the two lights.  For example: the wheels and horse christmas lights aren't moving, they just look like it because the lights create the illusion of movement.

Binocular Cue : Convergence

 
Convergence is when your eyes must move slightly inward or converge. They do this so that people are able to determine if objects are close to them or far away. An example is when people move a pencil close to their face and look at it with both their eyes. Through this little experiment they are able to determine whether the object is close or far from them.

Stroboscopic movement

Stroboscopic movement is where the brain perceives movement as a rapid series of varying images.  This creates the illusion that the object is moving, but the motion we see is actually made in our heads.  In the picture, the person looks like they're moving their arms, when in reality, there are just many pictures of a human being put together to make it seem like their arms are moving.

Biinocular Cue : Retinal Disparity

Retinal Disparity is the difference in images that the two eyes see due the the different angles that the eyes see the world. In this picture it shows how two different images are received by each of they eyes. This shows how retinal disparity works due to the angle the eyes see.

Monocular Cues : Linear Perspective

Linear perspective is when a set of parallel lines go for a long distance and seem to converge into one single line. A good example of this is a railroad track, if looked at from a certain angle the tracks seem to become one at a certain point.

Monocular Cues. : Interposition

Interposition is when an overlap of something causes us to perceive depth in an object. Probably the most well known example of this is an eclipse. The moon eclipses the sun which causes us to perceive depth of the sun and the moon

Monocular Cues : Relative Clarity

Relative Clarity is when we believe that hazy objects appear farther than sharp clear objects which appear to be closer. In this picture the person with the basketball appears to be farther due to their appearance being hazy. The tricks the mind into thinking that the person is farther than they actually are.

Monocular Cues: Relative Height

Relative Height is where distant objects appear to be smaller and higher in compared to items that are closer. In this picture the gravestones that are farther away from the front appear to have a smaller height than that of the gravestones closer to the camera.

Monocular Cues : Relative Size

                
A monocular cue is a part of depth of perception which allows us to perceive the distance of an object. There are different varieties of monocular cues, one monocular cue is called relative size. If two objects are known to be the same size but their absolute size is unknown, relative size cues can provide information about the relative depth of the two objects. So in this picture and in real life when the moon is closer to the horizon people believe that it is larger due to their relative size, but when the moon is in the sky there is nothing to compare it to so it seems to be smaller. This type of relative size illusion is called a lunar illusion.

Continuity

Continuity

Continuity is how we usually perceive smooth and continues patterns that do not change direction or make jagged turns. This is seen here because these intersecting train tracks are viewed as two lines going straight through two other lines and then continuing. Instead of viewing the as two V shaped figures that touch each other then go away from
