Automatic Leaf Segmentation for Estimating Leaf Area and Leaf Inclination Angle in 3D Plant Images

Italian National Conference on Sensors, 2018
Automatic and efficient plant monitoring offers accurate plant management. Construction of three-dimensional (3D) models of plants and acquisition of their spatial information is an effective method for obtaining plant structural parameters.

Relationships between leaf traits and morphological attributes in one-year bareroot Fraxinus angustifolia Vahl. seedlings

Annals of Forest Research, 2014
Leaf traits were investigated as morphological attributes for quality estimation of one-year-old bareroot seedlings of Fraxinus angustifolia Vahl. Leaf traits (number of simple – NSL and compound leaves – NCL, leaf average – ALA and total area – TLA and ...

Tree mortality across biomes is promoted by drought intensity, lower wood density and higher specific leaf area.

Ecology Letters, 2017
Drought events are increasing globally, and reports of consequent forest mortality are widespread. However, due to a lack of a quantitative global synthesis, it is still not clear whether drought-induced mortality rates differ among global biomes and ...

Estimating Leaf Area Density of Individual Trees Using the Point Cloud Segmentation of Terrestrial LiDAR Data and a Voxel-Based Model

Remote Sensing, 2017
The leaf area density (LAD) within a tree canopy is very important for the understanding and modeling of photosynthetic studies of the tree. Terrestrial light detection and ranging (LiDAR) has been applied to obtain the three-dimensional structural ...

Functional traits of tree saplings and adults in a tropical cloud forest restoration context

Botan‪ical Sciences, 2020
Background: The use of tree species’ functional traits is a promising approach in forest restoration. However, some traits may change during ontogeny. Questions: Does intraspecific variation in functional traits occur between sapling and adult stages?

PHOTOELECTRIC APPARATUS FOR MEASURING LEAF AREAS [PDF]

Plant Physiology, 1935
The need to measure accurately the area of several thousand apple leaves in connection with a study of the deposit of spray residues led to a search of existing methods of leaf area measurement. The several methods described in the literature failed to satisfy the requirements, inasmuch as accuracy in area measurements was apparently to be secured only

Geometrical parameter calculation of excised wheat leaves based on image analysis

浙江大学学报. 农业与生命科学版, 2018
Aiming at some deficiency of geometrical parameter calculation in plant leaves at present, we proposed a computational method suitable for measuring area, length, width and perimeter of excised wheat leaves.
