Fusion of Hand-Engineered and Deep Learning Features for Tuberculosis Detection from Chest X-Ray Images


Tuberculosis detection from chest X-Ray images is an important and yet very dreary task to be done manually for physicians as the number of patients is increasing day by day. In this regard, a computer-aided diagnosis system can facilitate the process to diagnose this increasing number of patients in a shorter time. For reliable detection of abnormality in chest XRay, different handcrafted features are used previously because of their low complexity in the extraction procedure and higher accuracy even in a small dataset. On the other hand, deep learning (DL) features gain popularity in many computer vision tasks because of their inhuman performance in comparison to the hand-engineered features. However, the extraction of high level DL features totally depends on the availability of a larger training set. Considering all these facts, we proposed a method that utilizes both the hand-engineered and deep learning-based features together for the tuberculosis detection task. The major finding of this work is that a combination of these two types of features having different error profile can provide better accuracy than their performance individually. The features from both processing arms are selected based on their quality in term of standard performance measure criteria and then ensembled utilizing Random Forest classifier to classify the x-ray images. The performance of this proposed method is evaluated on the set of chest x-ray images collected by Shenzhen hospital, China. The final accuracy and area under the ROC curve (AUC) indicates that it outperforms most of the state of the art methods.
