该算法有着较强的分类能力

可以极大地提高医学图像分类的效率和准确性.

Abstract

A medical image classifier is proposed in this paper.Gradient Vector Flow (GVF) is used to segment tumor area

and the texture and shape features are the inputs to classifier.A novel SVM algorithm is presented in this paper

which solves the problem that SVM has a poor performance when the two-class problem samples are very unbalanced.The experimental results indicate that the modified algorithm has a strong capability of classification for the unbalanced samples

and the efficiency and accuracy in the medical images are greatly improved.
