“…For example, the use of different imaging techniques has been proposed for plant phenotyping; see Li, Zhang, and Huang (2014) for a review. The most popular imaging techniques are based on single-lens cameras (Quan et al 2006;Paproki et al 2012), time-of-flight cameras (Chéné et al 2012;Alenyà et al 2013;Chaivivatrakul et al 2014;Xia et al 2015), or multi-view stereo imaging systems (Golbach et al 2015;Lou et al 2015;Rose, Paulus, and Kuhlmann 2015). All these methods allow the reconstruction and measurement of single leaves, although some of them require manual interaction (Quan et al 2006;Golbach et al 2015;Rose, Paulus, and Kuhlmann 2015) or prior knowledge of the plant (Chéné et al 2012;Chaivivatrakul et al 2014).…”
