Re: Clever image processing algorithm
Other algorithms in use are:
1) One to remove shadows cast by the veins in front of the retina. Under the right conditions you can observe these in your own eye, for a second or two until the filter algorithm kicks in.
2) One to increase the effective resolution of the eye by using saccades (microscopic eye movements) and combininging successive images to interpolate data in the gaps present in a single image.
3) One to filter out white blood cells in those pesky veins in front of the retina. Can sometimes be seen as white "floaters" when looking at a clear blue sky, which can defeat the filter.
If you wish to believe in a deistic creator, then you have to accept that He came up with some damned clever image processing algorithms to compensate for the shitty design of the eye.
Big hint for those who object to the preceding paragraph: the eye of the octopus is structurally almost identical to the vertebrate eye (we are vertebrates, as are all other mammals, reptiles, birds, amphibians and fish) except it isn't fucked up by being wired backwards (like ours is). According to the Babble, God created sea creatures before land creatures, so he had the octopus eye worked out before he created reptiles, birds and mammals but gave all of them the fucked-up design anyway.
