In the present paper, an expert system for automatic recognition of different plant species through their leaf images is investigated by employing the ant colony optimization (ACO) as a feature decision-making algorithm. The ACO algorithm is employed to investigate inside the feature search space in order to obtain the best discriminant features for the recognition of individual species. In ord...

Multiple features such as the margin, the shape and the texture of plant leaves are of great importance for classification of plant species, as they are often regarded as the unique features to identify plants. In this paper, we study the performance of a recently proposed semi-supervised fuzzy clustering algorithm with feature discrimination for leaf classification, based on features generated...

This paper describes an optimal approach for feature extraction and selection for classification of leaves based on Genetic Algorithm (GA). The selection of the optimal features subset and the classification has become an important methodology in the field of Leaf classification. The deterministic feature sequence is extracted from the leaf images using GA technique, and these extracted feature...

The deep green heart shaped leaves of betel vine are popularly known as a Paan in India. It is used in a number of traditional remedies. Now a day’s customer’s lifestyles and needs have gone through tremendous changes. These changes are new challenges for the farmers whose produce has to meet the customers demand. Concern to Betel producers the size and color of leaf is important factors to cat...

'Huangjinya' is an excellent albino tea germplasm cultivated in China because of its bright color and high amino acid content. It is light sensitive, with yellow leaves under intense light while green leaves under weak light. As well, the flavonoid and carotenoid levels increased after moderate shading treatment. However, the mechanism underlying this interesting phenomenon remains unclear. In ...

Autumn coloring of deciduous broad-leaved trees in northern Japan was found to develop either from the inner part of the crown outward (inner-type), or from the outer part of the crown inward (outer-type). Inner-type trees had early-successional characteristics, whereas outer-type trees had late-successional characteristics. Although alders (Alnus hirsuta (Spach) Rupr. and A. japonica (Thunb.) ...
