Multimodal Corpus Callosum Classification with Derived Features
In my previous post I detailed methods for conducting a binary image segmentation of the corpus callosum. I used three different image modalities (T1-weighted, T2-weighted and generalized fractional anisotropy) and a simple k-Nearest Neighbors (kNN) model from sklearn. We also covered some basic normalization that is important for kNN models.
Today’s goal is to demonstrate how some knowledge of your dataset can help you derive informative features.
In our dataset, we need to deal with some misclassified tissue from my last post on the corpus callosum.
