ANN: mahotas 0.9.7

[Luis Pedro Coelho]

Hi list,

Last month there was no mahotas release (because of the holidays at the
end of last year, development slowed down), but here is this month's
version: 0.9.7

This version adds a bunch of small features. Most interesting is Bernsen
local thresholding.

Full ChangeLog:

* Add ``haralick_features`` function
* Add ``out`` parameter to morph functions which were missing it
* Fix erode() & dilate() with empty structuring elements
* Special case binary erosion/dilation in C-Arrays
* Fix long-standing warning in TAS on zero inputs
* Add ``verbose`` argument to tests.run()
* Add ``circle_se`` to ``morph``
* Allow ``loc(max|min)`` to take floating point inputs
* Add Bernsen local thresholding (``bernsen`` and ``gbernsen`` functions)


Mahotas
-------

Mahotas is a computer vision library. Algorithms operate on numpy
arrays, but are implemented in C++ for speed (efficiency is a major
concern of mahotas).

It includes algorithms such as watershed, morphological operations,
feature computation (Haralick features, Zernike moments, and SURF), and
other tidbits.

Mmmm...

Unfortunately, I think I would need the full error message to be able to
tell you more.

On Windows, I recommend the well-maintained versions of Christoph Gohlke

Jose,

You can easily upgrade using pip.  If you don't have pip installed on windows you can do so by using:

easy_install pip

pip install --upgrade https://github.com/luispedro/mahotas/archive/release-0.9.7.zip

If you can't seem to run easy_install you may also have to install setuptools if you haven't already:
