A hybrid classifier, derived from iterative Fishers linear discriminant analysis coupled with the volume sphering analysis and support vecter machine, was developed to effectively segment multi-slice data of multispectral brain MRI by using only one set of training samples. The proposed method has several advantages. One was a reduction of computational cost in data processing since it only needs one set of training samples to process the entire multislice images. Besides, the same saving is also applied in minimizing operator burden. The uppermost benefit is to avoid operator interferences from selecting training samples and improve the reproducibility.
