I am doing a Computer Vision project which is a Pneumonia Detector using X-ray scan. So far my code is making use of a pre-trained model VGG16 to do image classification to classify if the Xray image contains pneumonia. But i also want my model to be able to highlight where the source of pneumonia is. I have heard of both VGG16 and yolo but im not sure how to integrate them so i need some advice on how to do it. Thanks.
