Localization of intervertebral lumbar discs

Abstract

Aim of this study is to localize intervertebral discs from MR images. The study implements a system that uses HOG-SVM based method which was used in previous studies. In addition to this, the study uses projection method to obtain better results. Intensity values of MR images can vary from sample to sample. HOG features provide better results by using gradient values instead of using pure intensity values. Vertical and horizontal gradient information is used through the features obtained by projection method. This information provides better detection results. © 2012 IEEE. © 2012 Elsevier B.V., All rights reserved.
