Measuring interpolated image intensity at subpixel positions

How can I measure image intensity values provided I have coordinates x,y,z (as double or float) and a given image?

For example, I'd take a distance map and a table with coordinates, then I'd like to measure for each row in the coordinate table the corresponding value in the distance map image.

In ImageJ, I would try to take a


to get an interpolated


, but I figured I'd ask first if something like this exists already in KNIME. Thanks for any advice how to go about this.

Hi Jan,

this is not possible, yet. But we are working on it. I will let you know as soon as we have support for real-coordinate images in KNIME.
