... ehhh... I would prefer 2d rgb to be the default in general as I think that is the generl use case? . This calls for a discussion imho. On Mon, Mar 11, 2013 at 3:36 AM, Stéfan van der Walt <stefan@sun.ac.za>wrote:

I want to modify SLIC to handle 3D images. However, it now become rather tricky to automatically detect whether the final dimension is channels or just z, in the case of image.ndim == 3 (ie, is this a 3D grayscale image, or a 2D RGB image?). I was trying to do something automatically (image.ndim == 3 and image.shape[-1] == 3) but I think maybe the easiest thing is to add a "has_channels" argument, defaulting to...? I want to say False, but

just my own biases. =)

In `random_walker`, we've opted for "multichannel=False":

data : array_like Image to be segmented in phases. Gray-level `data` can be two- or three-dimensional; multichannel data can be three- or four- dimensional (multichannel=True) with the highest dimension denoting channels. Data spacing is assumed isotropic unless depth keyword argument is used.

multichannel : bool, default False If True, input data is parsed as multichannel data (see 'data' above for proper input format in this case)
