Backpropagation Performance Against Support Vector Machine in Detecting Tuberculosis Based on Lung X-Ray Image

摘要

Tuberculosis (TB) is known as an infectious disease caused by bacterium Mycobacterium Tuberculosis. It is one of the highest diseases that occur in Indonesia. The lung disease can be identified by analyzing the x-ray image of the lung. The problem that followed is that the x-ray imageswere analyzed separately by the specialist physician at separate times, so the patient should consult a doctor after getting the x-ray image. In this study, we create a modeling design that can detect TB disease early by using artificial neural network method that is backpropagation by using Matlab Software, furthermore analyze the performance of the modeling based on the level of accuracy. In training process this system uses 441 images while for the test used 221 x-ray images. The system's phases were started with preprocessing including median filter process and histogramequalization to improve image quality. The results of preprocessing is then classified with Backpropagation algorithm through training process. The results showed that TBC detection system can be built using backpropagation method with 4400 hidden layer hidden neurons with accuracy of 81.45% from the test process result. The accuracy of NN Backpropagation is better than SVM method whose accuracy reachesof 78.73%.
