Nuclei Classification Trainig

This workflow reads images from a high throughput experiment acquired with an Olympus ScanR Microscope. A subset of the image data is used to train a classifier, which is then applied to the whole data setA classifier is trained on exemplary images and applied to the whole dataset.


NucleiClassification* example data can be found under the link in the description.* in the List Files Node specify the directory you want to work with.* select images with the two row filters in order to train a classifier. At the moment, the first row filter selects a certain subposition, the second a specific row.* open the Labeling Editor and define a training set by creating new classes and clicking on the according objects in the image. Refer to the help of the node for details.* run the rest of the workflow to classify the whole dataset.* Configure the Excel Writer to save your data accordingly. de.NBI Acknowledgement:If you like this workfllow and want to acknowledge it in your work, please do so!
