hallo, can anybody help me with this; I think i have to post in this mail list because i think i have to use numpy to do it.
I have a grayscale (L mode) image. On some places on the image i want to calculate the average pixel value (i know how to do that). But i want to let the user of the program choose the place! So i want that the user get a square on his mouseclick en be able to select the square where python has to calculate the averagepigelvalue. any ideas how i would do this? thanks in advance everybody 2010/4/8 Michael Gilbert <michael.s.gilb...@gmail.com> > On Thu, 8 Apr 2010 09:06:16 +0200, ioannis syntychakis wrote: > > thanks for all your answers. > > Now i can get al the values above the 150, but i would also like to have > > their positions in de matrix. > > > > excample: > > > > [[1. 4. 5. 6. 7. 1 > > 2. 5. 7. 8. 9. 3 > > 3. 5. 7. 1. 3. 7]] > > > > so, if i now look for values above the 8. the ouput should be; 1 value on > > position (4,1) (beginnning from 0) > > a == 8 > _______________________________________________ > NumPy-Discussion mailing list > NumPy-Discussion@scipy.org > http://mail.scipy.org/mailman/listinfo/numpy-discussion >
