You are the subject of this week's lab. You will write programs to generate several artifical images, then report what you perceive when you view them.

The human visual system employs its own complex image processing paradigms. Many of the effects you perceive in this lab are due to the response of your retinal cells, and take place long before the image reaches your visual cortex.

You will take a look (literally) at mach bands, a sinusoidal grating, and center/surround fileds for simultaneous contrast and Weber's Law, which are artificial images used to evaluate the response of the eye. The majority of your effort should focus on explaining why you see what you see, based on widely accepted models of human visual perception.

The programming for this lab is very simple, and should take around an hour. Good Luck !!
