Re: Vectorizing a summation

[rdelgado]

Hi,

What I am trying to vectorize is a definition of distance between images. X
and Y are MxN images, that are converted to MxN vectors. Then there is
another definition: |Pi-Pj| = sqrt( (k-k')^2 + (l-l')^2 ) that is, the
distance between pixels in position (k, l) and (k', l') from a MxN image.
The final calculation is:

Distance^2 = Sum (from i, j=1...MxN) [ exp(-|Pi-Pj|) * (Xi-Yi) * (Xj-Yj) ]

As you can see, I am a little confused of the definition.

Is it more clear now?

Thanks!
