Beginner in python and mahotas

[j***@public.gmane.org]

Hi!

I have a large number of 2-D pictures in ASCII format (.asc) and I want to
use Mahotas to calculate Haralick textures. But since I lack experince IŽm
having a hard time to make it work, so I hope you guys can help me out.

1. What does f refer to, how do I know the ndarray of integer type?

mahotas.features.haralick(*f*, *ignore_zeros=False*, *preserve_haralic
k_bug=False*, *compute_14th_feature=False*)

2. Haralick textures are often calculated in four directions, can I get one
output for all the directions, how does the output code look like?

Apologies if this is laughable easy for you,

Best regards

f is your input image. It needs to be an integer numpy array.

I don't really know how you'd load your ASCII format, you'd have to figure that one out yourself.

Perhaps you should spend some time with numpy tutorials before considering images.

You get the four dimensions separately.
