Mahotas

Mahotas comes packed with algorithms for processing images.

They were implemented in C++ for speed and use numpy arrays to operate.

The main algorithms are Otsu thresholding and watershed.

What is new in this release:

• Add labeled.bbox function
• Add `return_mean` and `return_mean_ptp` arguments to haralick function
• Add difference of Gaussians filter
• Add Laplacian filter
• Improve memory handling in freeimage.write_multipage
• Fix moments parameter swap
• Fix crash in median_filter when mismatched arguments are passed
• Fix gaussian_filter1d for ndim > 2

What is new in version 1.2.4:

• Added PIL based IO.

What is new in version 1.1.1:

• Fixed crash in close_holes function.

What is new in version 1.1.0:

• Better error checking
• Fix interpolation of integer images using order 1
• Add resize_to & resize_rgb_to
• Add remove_regions_where function
• Fix hard crash in convolution
• Fix axis handling in convolve1d
• Add normalization to moments calculation
• Add coveralls coverage
• Fix SLIC superpixels connectivity

What is new in version 1.0:

• Fixed tests in Python 3.
• Fixed a few corner cases in texture analysis.
• Integrates with Travis.
• Updated citation (include DOI).

What is new in version 0.9.4:

• Fixed compilation on 32-bit machines.

What is new in version 0.9.2:

• Fix compilation on Mac OS X 10.8
• Freeimage fixes on Windows
• Slightly faster _filter implementaiton

What is new in version 0.9.1:

• Python 3 support (you need to use ``2to3``).
• Haar wavelets (forward and inverse transform).
• Daubechies wavelets (forward and inverse transform).
• Corner case fix in Otsu thresholding.
• Add soft_threshold function.
• Have polygon.convexhull return an ndarray (instead of a list).
• Memory usage improvements in regmin/regmax/close_holes.

What is new in version 0.9:

• Auto-convert integer to double on gaussian_filter (previously, integer values would result in zero-valued outputs).
• Check for integer types in (reg|loc)(max|min) Use name `out` instead of `output` for output arguments. This matches Numpy better.
• Switched to MIT License.

What is new in version 0.8.1:

• Fixed gaussian_filter bug when order argument was used.
• Added morph.cerode.
• Improved regmax() & regmin(). Rename previous implementations to locmax() & locmin().
• Fixed erode() on non-contiguous arrays.
