Abstract

 This paper presents a computer-aided-detection system of osteoporosis. The proposed technique is implemented and
applied to
79 proximal femur radiographs. A dual-energy xray absorptiometry (DEXA) scan is used to measure T-score
of the images as a justification. Three feature extraction techniques are introduced to describe trabecular pattern
changes in proximal femur recorded: wavelet-based hierarchical pyramid, Gabor filter, and intensity gradient map.
The selected features were utilized in the design and training of support vector machine (SVM) classifier. The accuracy,
sensitivity, and specificity are used to measure the quality of the proposed detection system. The best result and detect
femur bone fractures and osteoporosis were obtained efficiently by using wavelet-based hierarchical approach
combined with Gabor filter, and intensity gradient map features. The proposed system showed superior performance
as compared to other related work.
