hmeine / geomap Goto Github PK

pythonutil.hxx contains a collection of BPL-related hacks and workarounds. Let's see whether it is needed at all now.

The individual files should contain license headers. See #8

During import, one currently gets:

/Users/hmeine/local-Darwin/lib/python2.7/site-packages/vigra/__init__.py:104: RuntimeWarning: to-Python converter for vigra::TinyVector<double, 2> already registered; second conversion method ignored.
  import vigranumpycore
/Users/hmeine/local-Darwin/lib/python2.7/site-packages/vigra/__init__.py:104: RuntimeWarning: to-Python converter for vigra::TinyVector<double, 3> already registered; second conversion method ignored.
  import vigranumpycore
/Users/hmeine/local-Darwin/lib/python2.7/site-packages/vigra/__init__.py:104: RuntimeWarning: to-Python converter for vigra::Point2D already registered; second conversion method ignored.
  import vigranumpycore

Before the restructuring, one could check out the hg repository into vigra/vigranumpy/private and issue "make geomap".

It would be great to get that working again. (We would probably want to build a DLL in the src/geomap folder first, and link against it.)

I removed the geomapmodule.cxx though, because it contained loads of unrelated functionality, so I first need to separate the bits and pieces and check in the GeoMap-related part of it.

At the moment this library uses with sigc++ for signals. However, an implementation using boost signals would also be interesting.
My current plan is:

• Add cmake option to select sigc++ or boost signals (maybe non exclusive?)
• Add switches to use boost signals or sigc++ across all code (non-exclusivity would be an important decision for this)

I am working on this here.

I got a strange crash when iterating an edge. In particular, I get no output with a loop like

for p in edge:
  print p

and I cannot do list(edge) or numpy.asarray(edge). Strangely, plot(*numpy.asarray(edge).T) works (consistently), but of course that may just be undefined behavior.

So far, we have not publicly attached a license to this repository.

Hi Hans,

I just stumbled over some very old code of mine, and now I'm trying to make it just run again.
I get some error messages at crackConvert.py, in crackEdgeMap:

File "geomap/subpixelWatersheds/crackConvert.py", line 22, in crackEdgeMap
    for dart in result.face(0).holeContours().next().phiOrbit():
AttributeError: '_ContourIterator' object has no attribute 'next'

Which is true, of course.
AFAICS, sortEdgesDirectly() and marking the border edges are processed in crackedgemap.cxx, CrackEdgeMapGenerator::initializeMap already, making the crackEdgeMap in crackConvert.py a three liner:

def crackEdgeMap(labelImage, initLabelImage = True, eightConnectedRegions = True):
    result = crackEdgeGraph(labelImage, eightConnectedRegions = eightConnectedRegions)
    result.initializeMap(initLabelImage)
    return result

That's all for the moment. :-)

For a long time, (Python) unit tests were lumped together in one (or a few) big file, without obvious relation between the modules being tested and the tests itself. We should

• separate the tests into several files, probably in appropriate subdirectories
• make sure there are no duplicates (e.g. from previous splitting work)
• and make the tests work again, of course.
  (And write new ones, but that's not this issue.)
