Detecting pneumonia in lung x-ray images (CXR) is still a complex challenge. It is influenced by various factors such as the variation of pneumonia itself and the state of the patient in the imaging process. Although there have been many efforts to improve the detection evaluation results, there is still room for further exploration from a modeling and pre-processing perspective to overcome such complexity.
The DETR model is an object detection approach that utilizes the transformer architecture of the image. In this study, the DETR model is compared with the Faster-RCNN model to evaluate the performance of both models in detecting the location of penumonia. In addition to the model, this research also evaluates the test in terms of pre-processing. Among them, DCP (Dark Channel Prior) is used to remove excessive haze in X-ray images, while CLAHE (Contrast Limited Adaptive Histogram Equalization) is applied to adaptively enhance image contrast. Each testing scheme is evaluated using the mean average precision (mAP) value.
Experimental results show that the DETR model converges faster than Faster-RCNN. Testing with the original data, DETR obtained an mAP of 55.52% and Faster-RCNN 33.91%. For pre-processing testing, the best result of DETR model is obtained in DCP method with mAP 55.7% and Faster-RCNN model is obtained in CLAHE method with mAP 34.08%. This shows that DETR produces better evaluation values. DCP succeeded in improving the mAP of DETR and CLAHE succeeded in improving the mAP of Faster-RCNN.
