Mahotas

* Use matplotlib as IO backend (fallback only)
* Compute dense SURF features
* Fix sobel edge filtering (post-processing)
* Faster 1D convultions (including faster Gaussian filtering)
* Location independent tests (run mahotas.tests.run() anywhere)
* Add labeled.is_same_labeling function
* Post filter SLIC for smoother regions
* Fix compilation warnings on several platforms

* 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)

* Fix distance() of non-boolean images (issue 24 on github)
* Fix encoding issue on PY3 on Mac OS (issue 25 on github)
* Add relabel() function
* Add remove_regions() function in labeled module
* Fix median_filter() on the borders (respect the `mode` argument)
* Add mahotas.color module for conversion between colour spaces
* Add SLIC Superpixels
* Many improvements to the documentation

* Fix compilation in older G++
* Faster Otsu thresholding
* Python 3 support without 2to3
* Add `cdilate` function
* Add `subm` function
* Add tophat transforms (functions `tophat_close` and `tophat_open`)
* Add `mode` argument to euler() (patch by Karol M. Langner)
* Add `mode` argument to bwperim() & borders() (patch by Karol M. Langner)

* Fix compilation on 32-bit machines (Patch by Christoph Gohlke)

* Fix interpolation (Report by Christoph Gohlke)
* Fix second interpolation bug (Report and patch by Christoph Gohlke)
* Update tests to newer numpy
* Enhanced debug mode (compile with DEBUG=2 in environment)
* Faster morph.dilate()
* Add labeled.labeled_max & labeled.labeled_min (This also led to a
refactoring of the labeled_* code)
* Many documentation fixes
