HI John, looking at the wiki page it seems to me that the "inline images" for the 4th derivatives of Gaussian don't match the linked images (which I looked at to get a bigger look). The inline ones look like they might be exactly the same as the Gabor wavelet images, but I'm not confident enough in this kind of wavelet analysis to say that's not right :-)

EDIT: I actually looked at the html source, saw the paste problem and took the liberty of fixing it.

A general question: the vertical axis of the graphs is a log-scale. Does that affect how I should interpret the graph? (I don't know, I'm asking.)
