Creation of new specific column

KNIME Extensions
1

Hi dear,

I am working on 3 images. After a segmentation we have a table where we can find in the rowID : Row 0 #1, Row 0 #2,..., Row 1#1, Row1#2,..., Row2#1, Row2#2,...,Row2#30. Well, Row0, Row1, and Row2 correpond to the 3 images and #1 #2 #3 correpond to the segments in each image. I would like to have a new column where all cells of the same image are named image1, and for the second image: image2 and for the third image: image3. Can you please tell me how we do that?

Thank you,

Hi ChakibO

 

Do you have a column "Source Labeling" in your table? If so you can use the "Labeling Properties"-Node to append the name of the Source Labeling which will be the input image name.

If you would like to sum up all segmented pixel of your images you can use the "GroupBy"-Node and group by (Groups Tab) "Source Labeling"-Column and aggregate (Manual Aggregation Tab) the number of pixel with the sum-operation.

 

Cheers

Tim

Hi Chakib,

I'd also like to point you on knime.imagej.net. There you find lots of information about KNIME and KNIME Image Processing which may help you!
