Construction of a classifier

Description

Creates a classifier for a training set.

Usage

createClassifier(trainingData, cross = FALSE)

Arguments

Details

Topological features include the density of cells and the size of the surrounding cytoplasma of a cell. These features depend on the size of the image. If training image and the image to classify have different size, these features can fool the classification and should not be enabled.

Value

A List containing:
