Transformers!

Being the quintessential Transformers fan that I am (read: borderline addict). I couldn’t help but take a trip down memory lane and write a post on Transformers and visual perception. Just as the theme song so candidly states, the transformers are “More than meets the eye.” This statement can be applied to visual perception because everything that is seen by our eyes does not represent everything that is present in the world. An example of this is the fact that we are only able to see a portion of the light spectrum. Another possible explanation for “more than meets the eye” is the manner of interpretation of factors such as vividness and contrast. What is at work here is the influence from our retinal ganglion cells and their on/off receptive fields. These RGCs provide valuable information about how light hits objects we are observing. The physical measurement of light bouncing off does not represent what our brain perceives.

Mach bands are an optical illusion in which bands of a light and dark color are separated by a thin band with a light to dark gradient. This narrow band is perceived as two different bands.

This optical illusion is more than meets the eye, just like transformers.

  3. [...] Sean sure does love the transformers and has some prose and a U Tube video to back it up. Caroline took a different approach and wrote about the transformation between what you see and what you perceive. [...]
