Webprojections. However, a critical challenge in the case of overlapping groups is the projection onto the set of group-sparse vectors is NP-hard in general. To alleviate this issue, we use the connection between submodularity and overlapping group projections and a greedy selection based projection is at least good enough. WebB. Greedy Projection Marton et al. [22] implemented a fast reconstruction method in the Point Cloud Library [23], that creates a surface by triangulating points after projecting them onto a tangential surface in an adaptive local neighborhood. This method is fast and has mechanisms to ease the addition of new

WebEfficiently computing the greedy triangulation is a prob-lem of long standing, going back at least to 1970 [9]. A number of the properties of the GT have been discov-ered [18, 22, 26, 27] and the greedy algorithm has been used in applications [5, 27]. A straightforward approach to computing the GT is Webprojections.
