(**args)[source]¶ Bases:
xmipp3.protocols.protocol_kerdensom.KendersomBaseClassify
Classifies a set of images using Kohonen’s Self-Organizing Feature Maps (SOM) and Fuzzy c-means clustering technique (FCM) .
The kerdenSOM algorithm anneals from an initial high regularization factor to a final lower one, in a user-defined number of steps.
KerdenSOM is an excellent tool for classification, especially when using a large number of data and classes and when the transition between the classes is almost continuous, with no clear separation between them.
The input images must be previously aligned.
