ExtractVoxelCoordinatesFromSegmentationMask.cxx: Wrong coordinate order when output is formatted as indices #1

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
When you run the program extractVoxelCoordinatesFromSegmentationMask with
the -i flag, i.e. the output is formatted as voxel indices instead of real
world coordinates, the x- and y-coordinates are swapped.

A 3D volume voxel with indices

index[0], index[1], index[2]

maps to real world coordinates as

f(index[1]), f(index[0]), f(index[2])

That is, you need to swap index[0] and index[1].

This is a non-issue.

Matlab has this problem, but ITK doesn't, the indices come in the correct order.

So no need to make any changes, and this bug report can be marked as "Invalid".
