HoG 기술자를 이용한 중이염 자동 판별 방법

Abstract

ABSTRACT This paper presents a decision method of middle ear disease which is developed in children and adults. In the proposed method, features are extracted from the middle ear disease images and normal images using HoG (histogram of oriented gradient) descriptor and the extracted features are learned by SVM (support vector machine) classifier. To obtain an input vector into SVM, an input image is resized to a predefined size and then the resized image is partitioned into 16 blocks each of which is partitioned into 4 sub-blocks (namely cell). Finally, the feature vector with 576 components is given by using HoG with 9 bins and it is used as SVM learning and classification. Input images are classified by SVM classifier based on the model of learning features. Experimental results show that the proposed method yields the precision of over 90% in decision. 키워드 : HoG, SVM, 중이염, 분류 Key word : HoG, SVM, Middle ear Disease, Classification Received 11 November 2015, Revised 14 December 2015,
