Hello Everyone! I have a question in Variance Filter. I am working some image processing in variance filter. I am getting this warning message WARN Variance Filter 3:3 No columns of type ImgPlusValue available!. Can you help me to solve?
Hi @Vinothini and welcome to the KNIME community forum,
You need to have an image column of type “ImgPlusValue” passed to this node.
You can:
-
Read images using the Image Reader or Image Reader (Table) nodes from the Image Processing extension. These nodes will output ImgPlus.
-
Convert existing images to ImgPlus with the PNG Image to ImgPlus node.
Thank you for your valuable reply. It worked to solve my problem.
