This image morphology toolbox implements the basic binary and greyscale morphology operations, working with numpy arrays representing images.

This is a pure Python package which is the companion package to the book "Hands-on Morphological Image Processing." It has been updated to work with numpy and the names and interfaces have been Pythonised.

Includes basic operations such as - erode - dilate - open - tophat opening - watershed - ...

The package mahotas implements some of the same functions in C++ and, so, it is much faster (even if it is not as feature-full).

Status & Future Plans

The package is actively maintained and any reported bug will be fixed fast.

Currently there are no known bugs (although testing coverage is not complete).

When all functions have a corresponding unit test and the whole of the API documentation has been re-written into numpy rst format, I will release version 1.0.
