3D digital shapes are now ubiquitous, from industrial digital twins and mock-ups to virtual environments and characters. Unfortunately, they are mostly represented as a set of basic geometric primitives, such as points and polygons, without much global coherence. How can we recognise an object or its parts from such low-level information? This is the purpose of 3D shape understanding, which I will introduce in this talk with a specific focus on plants and trees. As an example, I will present a new citizen science app which allows one to compute various urban tree features from a single smartphone video.<\/p>\n\n\n\n

We are also inviting top experts in AI and Knowledge Technologies to discuss major socio-technological topics with an audience that comprises both members of the Knowledge Media Institute, as well as the wider staff at The Open University. Differently from our seminar series, these events follow a Q&A format.<\/p>\n<\/div>\n<\/div>\n<\/div><\/div>\n","protected":false},"excerpt":{"rendered":"
