Example with Gaussian Convolution

[izaychik63]

I try to run example on KNIME 3.7 and getting error
ERROR Gaussian Convolution 0:37 Error in row image1-mask.jpeg: java.io.IOException: No externalizer available with id ImageMetadataExt3
ERROR Gaussian Convolution 0:37 Execute failed: java.lang.RuntimeException: java.io.IOException: No externalizer available with id ImageMetadataExt3

What is missed on my installation?

Hi @izaychik63,

I am sorry you are encountering this bug, it looks like the example workflow was created with the nightly version of KNIME Image Processing. Can you tell me the name of the workflow so I can fix this?
You should be able to get the workflow running again, by resetting the nodes.

best,
Gabriel

The example was posted on forum (background-color.knwf).
Do you mean I can delete existing node and replace them with current KNIME nodes?

I see it’s the one I posted here:

Detecting Background Color

Hi @caceter, I am sorry for the delayed reply, but I was finally able to take a look at these images. I created a simple workflow that applies the mask to the image and then extracts the median pixel value of the background in each channel. background-color.knwf (474.7 KB) best, Gabriel

I have attached an fixed version:

Yes, or you can just reset the node, should have the same effect.

Thank you, Gabriel.
