Leaf Margin Analysis: Taphonomic Constraints
PALAIOS, 2005Abstract Leaf margin analysis (LMA), which is based on a correlation between the proportion of woody dicot species with non-toothed leaf margins and mean annual temperature, has been promoted as a tool for estimating mean annual temperature (MAT) from fossil-leaf assemblages.

Leaf wetness sensors - a comparative analysis
2015 9th International Conference on Sensing Technology (ICST), 2015Leaf wetness duration (LWD) is an important variable in plant disease prediction, which can promote the germination of fungal pathogen spores on leaf surfaces. There are different types of leaf wetness sensors (LWS) to measure LWD with no broadly accepted measurement standard.

Chinese Journal of Applied and Environmental Biology, 2012
In order to analyze the taxonomy,behavior and ecology of leaf mining insects by means of leaf mines which are the marks caused by larva miners' mining in leaves,the methods of GetData Graph Digitizer and R language were used to get the data of digitalized images of linear leaf mines and their shape parameters,including mean turn angle,concentration of ...

Plant Identification Using Leaf Image Analysis
SSRN Electronic Journal, 2018Plant identification is a vital task in areas such as medicine, botany and food sector. Leaves also play an essential role in plant species recognition. However, plant identification becomes more challenging in case of leaves with the complicated background having interferences and overlapping.

Phenotypic Analysis and Molecular Markers of Leaf Senescence
2018The process of leaf senescence consists of the final stage of leaf development. It has evolved as a mechanism to degrade macromolecules and micronutrients and remobilize them to other developing parts of the plant; hence it plays a central role for the survival of plants and crop production.

The molecular genetic analysis of leaf senescence
Current Opinion in Biotechnology, 1997The cloning of genes induced during leaf senescence and the study of their modes of regulation conducted in the past two years have revealed some of the molecular mechanisms underlying leaf senescence. The identification of genetic mutants that control leaf senescence in Arabidopsis thaliana opened up new possibilities for genetically analyzing leaf ...

Automated analysis of leaf venation patterns
2011 IEEE Workshop on Computational Intelligence for Visual Intelligence (CIVI), 2011Visual imaging methods have been lately extensively used in applications that are targeted to understand and analyze botanical patterns. There is a rich literature on imaging applications in the above field and various techniques have been developed. In this paper, we introduce a fully automated imaging approach for extracting spatial vein pattern data

Machine Learning for Plant Leaf Analysis
2016One of the key challenges for automated analysis of plant leaves lies in the range of variation presented by a species and even by a single plant (Fig. 2.1). As well as the natural variation to be expected from any organic object, the variation of a leaf can arise from a number of sources, for example, its age and developmental stage.

Multivariate analysis of leaf tissue morphogenesis
2020Leaf size and shape are strongly influenced by the growth patterns of the epidermal tissue. Pavement cells are the prevalent cell type in the epidermis and during cell expansion they undergo a drastic shape change from a simple polyhedral cells to puzzled-shaped cell.
