讲座摘要：This talk looks at 2 separate topics. Firstly, many papers assume, for simplicity, that the noise in range scanners is Gaussian, and independent from point to point. A series of experiments is described which test that assumption, and it is shown that the noise is not quite Gaussian, but much more importantly, it is highly correlated at nearby points. The implications of this for downstream tasks such as denoising is discussed. Secondly, we consider algorithms for removing noise from scanner data, while preserving sharp features.
