X-ray angiography is a common method for image-guided navigation comprising surgical devices and vessel contours detection which can offer visual feedback to physicians. However, for the sake of both physicians' and patients' health, the contrast agent is injected intermittently and in a low dosage, so the X-ray images are not always of adequate quality for visual examination. So the navigation, which...
This paper reports on a method to perform robust visual relocalization between temporally separated sets of underwater images gathered by a robot. The place recognition and relocalization problem is more challenging in the underwater environment mainly due to three factors: 1) changes in illumination; 2) long-term changes in the visual appearance of features because of phenomena like biofouling on...
This paper addresses the complete visual coverage path planning problem in raster terrain and presents an effective solution with hierarchy based on multiple observers siting and an evolutionary path planning algorithm. The main idea of the method is to get a nearly optimal complete visual coverage path by connecting all of the observers in the visual coverage set. Firstly a new deterministic algorithm...
