Current quantitative are either limited to tedious and sparse manual measurements, or coarse image-based 2D measurements. Availability of cheap and portable 3D acquisition devices has the potential to automate this process and easily provide scientists with volumes of accurate data, at a scale much beyond the realms of existing methods. However, during their development, plants grow new parts (e.g., vegetative buds) and bifurcate to different components --- violating the central incompressibility assumption made by existing acquisition algorithms, which makes these algorithms unsuited for analyzing growth. We introduce a framework to study plant growth, particularly focusing on accurate localization and tracking topological events like budding and bifurcation. This is achieved by a novel forward-backward analysis, wherein we track robustly detected plant components back in time to ensure correct spatio-temporal event detection using a locally adapting threshold. We evaluate our approach on several groups of time lapse scans, often ranging from days to weeks, on a diverse set of plant species and use the results to animate static virtual plants or directly attach them to physical simulators.<\/jats:p>","DOI":"10.1145\/2508363.2508368","type":"journal-article","created":{"date-parts":[[2013,11,6]],"date-time":"2013-11-06T14:09:19Z","timestamp":1383746959000},"page":"1-10","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":74,"title":["Analyzing growing plants from 4D point cloud data"],"prefix":"10.1145","volume":"32","author":[{"given":"Yangyan","family":"Li","sequence":"first","affiliation":[{"name":"Shenzhen, VisuCA Key Lab\/SIAT"}]},{"given":"Xiaochen","family":"Fan","sequence":"additional","affiliation":[{"name":"Shenzhen, VisuCA Key Lab\/SIAT"}]},{"given":"Niloy J.","family":"Mitra","sequence":"additional","affiliation":[{"name":"University College London"}]},{"given":"Daniel","family":"Chamovitz","sequence":"additional","affiliation":[{"name":"Tel Aviv University"}]},{"given":"Daniel","family":"Cohen-Or","sequence":"additional","affiliation":[{"name":"Tel Aviv University"}]},{"given":"Baoquan","family":"Chen","sequence":"additional","affiliation":[{"name":"VisuCA Key Lab\/SIAT and Shandong University"}]}],"member":"320","published-online":{"date-parts":[[2013,11]]},"reference":[{"key":"e_1_2_2_1_1","doi-asserted-by":"crossref","unstructured":"Ahmed N.
