2Sensitivity analysis of parameters and contrasting performance of ground filtering algorithms with UAV photogrammetry-based and LiDAR point clouds显示文摘Most ground filtering algorithms are primarily designed for airborne LiDAR point cloud processing and their successful use in identifying ground points from photogrammetric point clouds remains questionable.We compared six ground filtering algorithms implemented in Metashape,ArcGIS,CloudCompare,LAStools,and PDAL.We used UAV photogrammetry-based(acquired under leaf-off conditions)and airborne LiDAR(leaf-on)point clouds of the same area to:(i)compare accuracy of generated DTMs;(ii)evaluate the effect of vegetation density and terrain slope on filtering accuracy;and(iii)assess which algorithm parameters have the greatest effect on the filtering accuracy.Our results show that the performance of filtering algorithms was affected by the point cloud type,terrain slope and vegetation cover.The results were generally better for LiDAR(RMSE 0.13–0.19 m)than for photogrammetric(RMSE 0.19–0.23 m)point clouds.The behavior in varying vegetation and terrain conditions was consistent for LiDAR point clouds.However,when applied on photogrammetric point clouds,the algorithms’behavior was inconsistent,especially in areas of steep slope(except for the Progressive Triangulated Irregular Network in LAStools).Parameters related to the selection of the initial minimum elevation ground points were the most influential in all algorithms and point clouds.Petr Klápště Michal Fogl Vojtěch Barták Kateřina Gdulová Rudolf Urban Vítězslav Moudrý 2020International Journal of Digital Earth2020,13,12:2
3Endothelin-1 activation in pediatric patients undergoing surgical coarctation of the aorta repair显示文摘AIM To determine endothelin-1(ET-1)concentration before and after surgical coarctectomy and evaluate its association with left ventricular geometric change.METHODSA prospective,cohort study of 24 patients aged 2 d to 10years with coarctation of the aorta undergoing surgical repair.A sub-cohort of patients with age<1 mo was classified as'neonates'.Echocardiograms were performed just prior to surgery and in the immediate post-op period to assess left ventricle mass index and relative wall thickness(RWT).Plasma ET-1 levels were assessed at both time points.Association between ET-1 levels and ventricular remodeling was assessed.RESULTSPatients<1 year demonstrated higher pre-op ET-1 than post-op(2.8 pg/m L vs 1.9 pg/m L,P=0.02).Conversely,patients>1 year had no change in ET-1 concentration before and after surgery(1.1 vs 1.4,NS).Pre-op,patients<1 year demonstrated significantly higher ET-1 than older children(2.8 vs 1.1,P=0.001).Post-op there was no difference between the age groups(1.9 vs 1.4,NS).Neither RWT nor left ventricle mass index(LVMI)varied from pre-op to post-op.The subset of neonates showed a strong positive correlation between pre-op ET-1 and RWT(r=0.92,P=0.001).Patients with ET-1>2 pg/m L preop demonstrated higher LVMI(65.7 g/m^(2.7) vs 38.5 g/m^(2.7),P=0.004)and a trend towards higher RWT(45%vs39%,P=0.07)prior to repair than those with lower ET-1concentration.CONCLUSIONET-1 concentration is significantly variable in the perioperative period surrounding coarctectomy.Older children and infants have different responses to surgical repair suggesting different mechanisms of activation.Benjamin Steven Frank Tracy T Urban Suhong Tong Courtney Cassidy Max B Mitchell Christopher S Nichols Jesse A Davidson 2017World Journal of Cardiology2017,9,12:2
