Counting image segments

KNIME Extensions
1

I am very new to image processing in KNIME, so I am struggling with what is probably a simple query - following a Global Threshold -> Connected Component Analysis, I am looking to append a column to my table indicating how many segments each image is divided into.

How is this achieved?

Thanks,

Alastair

Hi Alastair,

there are several ways to do that:

* Labeling Properties -> Label Count

* Segment Feature Node (just execute it) followed by GroupBy with Source Labeling as Group and Counting of Labels as Aggregation method.

Does this help?

PS: A nice example for counting can be found at http://tech.knime.org/community/image-processing "Counting Chromosomes".

Hi Christian,

Thanks, that looks perfect. I am watching your Image Processing webinar as I type, and have also got the Counting Chromosomes example to work through.

Regards,

Alastair

Great! We are currently working on some really useful stuff concerning the ImageJ2 integration, Documentation and new nodes. I hope there will be a really nice release by the end of january!

However, if you have any further questions, feel free to ask.

Christian
