Leaf Vocabulary: Fine-Grained Leaf Image Retrieval Using Bag-of-Visual-Words Representation
This paper addresses the issue of fine-grained leaf image retrieval (FGLIR) which focuses on differentiating between different leaf cultivars within the same species. We investigate a novel bag-of-visual-words approaches (BoVW) to FGLIR.

Mutational spaces for leaf shape and size [PDF]
A key approach to understanding how genes control growth and form is to analyze mutants in which shape and size have been perturbed. Although many mutants of this kind have been described in plants and animals, a general quantitative framework for describing them has yet to be established.

Automatic leaf segmentation and overlapping leaf separation using stereo vision
Farm management and crop quality assessment is becoming increasingly automated to keep up with demand. The physical examination of the plant leaves, stems and fruit can provide valuable information about a plant’s health. Automating the visual inspection

Seasonal Canopy Temperatures for Normal and Okra Leaf Cotton under Variable Irrigation in the Field
Temperature affects a number of physiological factors in plants and is related to water use, yield and quality in many crop species. Seasonal canopy temperature, measured with infrared thermometers, is often used in conjunction with environmental factors

Optimization of leaf morphology in relation to leaf water status: A theory
The leaf economic traits such as leaf area, maximum carbon assimilation rate, and venation are all correlated and related to water availability. Furthermore, leaves are often broad and large in humid areas and narrower in arid/semiarid and hot and cold ...

A general model for describing the ovate leaf shape
Many plant species produce ovate leaves, but there is no general parametric model for describing this shape. Here, we used two empirical nonlinear equations, the beta and Lobry–Rosso–Flandrois (LRF) equations, and their modified forms (referred to as the

Divergent leaf shapes among Passiflora species arise from a shared juvenile morphology
Not only does leaf shape vary between Passiflora species, but between sequential nodes of the vine. The profound changes in leaf shape within Passiflora vines reflect the temporal development of the shoot apical meristem from which leaves are derived and
