Yes, I am trying to write a OCR algorithm with neural network, but the
theories of NN is of little importance, what I am trying to get ready for
the project is run speed.
the problem comes in a number of ways:
first, as you mentioned, image.getpixel is not very fast, according to
so an alternative should be searched for,
also, I loop (x,y)
x = 0 -1023
y = 0- 768 through
and currently i use this:
x = 0
y = 0
for x in xrange(1, 1024, 1):
for y in xrange(1, 768, 1):
rgb = image.getpixel ((10, 12))
a while loop is slow than for, and then map is faster.
as for that this:
image.getpixel ((10, 12))
currently i only use the shell window itself, so i can't really loop
1024*768, that's why it's only
