Re: [Numpy-discussion] adaptive thresholding: get adacent cells for each pixel

Thanks for all the help!Convolving looks like a great way to do this, and I think that mean will be just fine for my purposes.That iterator also looks fantastic and is actually the sort of thing that I was looking for at first. I havn't tried it yet though. Any idea how fast it would be? StephenOn

[Numpy-discussion] finding connected areas?

label (http://tinyurl.com/fcnvd) that labels connected objects in a matrix. That seems like a good way to start, and I'm sure there is a way for me to do something similar in numpy, but how? Thanks Stephen Emslie ___ Numpy-discussion mailing list Numpy-

[Numpy-discussion] iterate along a ray: linear algebra?

I am in the process of implementing an image processing algorithm that requires following rays extending outwards from a starting point and calculating the intensity derivative at each point. The idea is to find the point where the difference in intensity goes beyond a particular threshold. Specif
