Haralick Features, and other features, too!

I found this site that describes a Python module that calculates Haralick textures, SURF features, and others.

Notable algorithms:

• watershed.
• convex points calculations.
• hit & miss. thinning.
• Zernike & Haralick, LBP, and TAS features.
• freeimage based numpy image loading (requires freeimage libraries to be installed).
• Speeded-Up Robust Features (SURF), a form of local features.
• thresholding.
• convolution.
• Sobel edge detection

PythonVision is another good site.
