JDWarner 99238c44a5 sqrt(gradients) line removed 2012-08-29 17:07:13 -05:00
JDWarner 61320957eb Changes based on PR review recommendations: input format, scaling, and bugfix. 
In this new version, all instances of 'spectrum' have been replaced with 'channel'.  The documentation also reflects this change, and the new multichannel kwarg used to indicate multichannel input is named appropriately.

New boolean multichannel kwarg added, which controls if the input has multiple channels or not.  Input 'data' is now array_like for both gray-level and multichannel.  This kwarg is needed mainly because a 3-D array could be either 3 spatial dimensions or a set of different 2-D channels.

New scaling kwarg added (may be removed in future), controlling if data scaling is applied to ALL channels or each channel individually, if multichannel=True. No effect for gray-level data.

Removed np.sqrt(gradients) in _compute_weights_3d(), which was a bug. Tests now pass consistently.

New method for maintaining shape from input to output, where dims = data.shape prior to np.atleast_3d().  A theoretical (70,100,1) array passed should now result in a (70,100,1) shaped output, for example.

Updated and fixed multispectral test script to work with new version.  TODO: Additional test(s) likely needed to cover code branches from new kwargs.
 2012-08-29 16:33:56 -05:00
JDWarner 682d0535cd Added multispectral random walker test. 
Since the multispectral path is equivalent except for gradient calcs,
only one test case is needed.  This test is modeled on the 3-D
non-multispectral version.  If deemed necessary, adding a 2-D case
would be simple.
