Detection of surgical devices, in particular of guide-wire detection, is prerequisite during image-guided navigation in percutaneous coronary intervention (PCI). Guide-wire detection is a challenging task for following reasons: (i) X-ray images have a low signal-to-noise rate (SNR); (ii) there is a high similarity between guide-wires and some other adjacent anatomical skeletons' contours; (iii) guide-wires...
The simulator based on interactive virtual reality can solve many drawbacks in traditional surgery training, and it is widely used to train apprentices. A real-time and realistic guidewire model is a challenging task for the simulator, which is used to simulate minimally invasive vascular surgery. In this paper, we propose a fast and stable physical model to simulate the behavior of the guidewire...
Image semantics have received more and more attention because of the huge gap between the low-level features and the semantics. Semantic image retrieval is a challenging problem and became a research focus. This paper presents a semantic image retrieval approach based on multiple-instance learning. In multiple-instance learning, the training samples are bags composed of instances without labels. The...
