The project focuses on two domains of medical image analysis, image segmentation and classification. Medical image segmentation is a process to determine regions or boundaries of objects of interest, which is the first step in many clinical decision systems. Medical image classification performs disease detection on medical images to assess the probability of certain diseases. In this project, two networks are proposed to improve the existing methods on multi-organ segmentation on x-ray and CT images and disease classification on chest X-ray images. Existing segmentation networks consist of an encoder to extract features from input images, while a decoder decodes the features and outputs pixel-wise segmentation masks. We proposed a generative adversarial segmentation network that improves the performance of traditional segmentation networks with the aid of unlabelled data. Inspired by segmentation networks, we have also proposed an attention-based classification network. The network utilises the location information, such as organ mask, region of interest (ROI) bounding box to improve the classification performance while generating disease localization heatmaps. | URI: | https://hdl.handle.net/10356/151137 | Schools: | School of Electrical and Electronic Engineering | Fulltext Permission: | restricted | Fulltext Availability: | With Fulltext |
