[mitk-users] What turns on the contour interpolation?

[Miklos Espak]

Hi,

when using our segmentation tools, sometimes the contour of the
segmented region changes and then the contour points are connected by
interpolation instead of straight lines.

I am wondering if this is a feature in MITK that we accidentally
activated by a key or mouse interaction. I would like to disable it,
but do not find the code that does that.

Anybody knows what is this interpolation thing and how to control it?

I attached two snapshots from a screen recording. One was taken before
the interpolation got switched on, the other one after that. I am
talking about the green contour. The orange contour is all right. (The
green control perfectly overlaps it, normally, that's why it is not to
see on the first screenshot.)

Cheers,
Miklos

Hi,

what is the corresponding helper object in the Data Manager? Maybe the name of it will point you to the right direction.

Best,
Stefan

Hi,

it is not the MITK segmentation tool but a completely different one with
different tools. The helper nodes are created on our side, so I know their
name and where we create them, but we do not set a property for the
interpolation. At least not directly from our code base, but there might be
a transitive call to MITK or VTK.

Cheers,
Miklos

Well, I would expect that the green contour must be held by a separate node somewhere, except that there is a mapper which generates to contours out of a single data item. I’m not sure if it is really an interpolated contour rather than a reduced one which would shed the light onto the ReduceContourSetFilter, which is used by the 3D interpolation, AFAIK.
