Random Forestを用いた白血球分画の自動分類システムの開発

Classifying leukocyte and examining their proportions is a very important for disease examination and diagnosis. This examination needs the knowledge of experts and a lot of time. Therefore, many automatic leukocyte images classification algorithms have been proposed. There is a method to classify 13 types blood cells using 1 vs 1 Support Vector Machine(SVM) in one of them. In the conventional method, leukocyte images are classified with the 26-dimensional feature vectors. However, the classification accuracy, is poor with these feature vectors in granulocytes in this method. In this paper, we propose new feature vectors to improve the classification accuracy of blast cells with low classification accuracy among the leukocyte fractions. That is, we add two feature vectors in the proposed method. And we improve the accuracy of the whole by using a random forest for the classifier.
