📄️ No Classification
If no classification is selected, the image is not classified and thus, the labels that have been drawn in the image are not changed but used directly in later post processing and information calculation.

📄️ Threshold
Using Threshold classification, it is possible to specify the upper and lower threshold values for each label. When specifying the threshold of several features, it is possible to obtain a more specific classification.
📄️ Bayesian
This method can be used if there is heavy variation throughout the data set. Under Type, choose between Linear and Quadratic classification. Linear classification discriminates between classes using straight lines. Quadratic classification uses 2nd degree polynomials for the discrimination.
📄️ Decision forest
The decision forest classifier can be tuned by adjusting the slider between Fast and Accurate. The values on the slider can be between 100 and 1, where 100 signifies a more advanced classifier 1 signifies a simpler classifier. It is often not necessary to use the most advanced decision forest to get satisfactory classification results.
📄️ K-means clustering
K-means Clustering is a very useful method to compensate for variation in Staining and Lighting throughout the dataset. To use K-Means clustering, the individual feature bands must be comparable (i.e. they must be approximately the same scale).
📄️ Detect Region Of Interest
Detect Region of Interest is a simple method that divides the image into sections, based on pixel intensity. This method is a useful tool for separation of the background and tissue.
📄️ Cell classification
Cell Classification is a useful tool for detecting individual cells. Ensure that a number of image classes for training have been created and labelled according to cell types in the images. Recall that more training labels, means that more data will be used to train the classifier. Thus, drawing many training labels, leads to a better performing classifier. Also recall that all image classes defined need to have drawn training labels of its type.
