back Knowledge transfer

Using knowledge transfer to obtain training data.

This method allows you to choose existing annotations of another volume as training data for the instance segmentation stage. This is done using the "knowledge transfer" method UnKnoT [1]. All annotations will be converted to circles and the new MAIA job will immediately proceed to the instance segmentation stage. This method can only be used if distance to ground or image area information is available for all images of the volume of the MAIA job.

UnKnoT using the image area is an extension of the original method that offers an alternative to using the distance to ground information.

Configurable parameters

To show all configurable parameters, click on the button below the form.

Volume

The volume of which to use annotations as training data for the instance segmentation stage. Only volumes with distance to ground or image area information for all images can be selected. The annotations should show the same or very similar object classes than those that should be found with the MAIA job.

Restrict to labels

By default, all annotations are used.

Use the input field to select one or more labels. If present, only annotations with the chosen labels are used as training data for the MAIA job. If no labels are chosen, all annotations are used.
