Reference Request: Human visual system takes in $10^7$ bits/sec at the periphery and compresses it down to 50 bits/sec deep inside In Sparse Components of Images and Optimal Atomic Decompositions by Donoho, 1998, the author claims that > The human visual system is thought to do a tremendous job in achieving sparse representation of image data, taking $10^7$ bits/sec at the periphery of the visual pathway and winnowing it down to about 50 bits/sec deep inside. Can somebody please point me to the source of that claim, as it is not mentioned in the paper, at least to my knowledge.

How about this: <

The original link in the Abstract referenced (< above isn't available anymore, but I found a repository:

I don't think the review is peer reviewed, but maybe you find a reference in there (it's not my field, so I guess you know more on where to look ;-)

She's now in Germany: <

If you don't find anything, maybe you can ask her on researchgate directly.
