ABSTRACT
Plants are very important to us. All food people eat comes directly or indirectly from plants. To effectively use plants, one must learn basic plant identification and classification skills. So it is necessary to establish database by information technology as soon as possible. The distinct feature of plant and their leaf motivate the researchers to perform research on it to accurately classify the plants. In this paper we present overview of various feature extraction technique and plant classification methods which can be useful for accurately classifying the plants. We review the computational morphometric that have been used in recent years to analyse images of plant leaf. In this paper we have discussed various plant species classification methods where leaf is classified based on its digital morphological features. Among the available methods of classification deciding the best one is really a difficult task because accuracy of the result is depend on the input data. The aim of this survey is to provide an overview of different plant leaf feature extraction and plant classification technique.
KEYWORDS: Morphological feature, plant leaf classification, feature extraction, moment feature.
I. INTRODUCTION
In order to recognize plant species from their shapes, color, textures and seedling, there have been many recent studies on plant classification and recognition. It is very difficult to analyze the shape of flowers and seedling because of their 3D structure if we consider only 2D images. So in this survey we have concentrated on plant species classification based on morphological features of leaf. Taxonomy relies greatly on morphology to discriminate groups. Computerized geometric morphometric methods for quantitative shape analysis measure, test and visualize differences in form in a highly effective, reproducible, accurate and statistically powerful way. Plant leaves are commonly used in taxonomic analyses and are particularly suitable to landmark based geometric morphometrics. Plant are useful for environmental protection. Due to deterioration of environment like global warming large number of plant species are at the margin of extinction. Many of rare plant species have died out. So it is necessary and urgent need to classifying plant species by its category to help botanist by establishing bio-diversity database. The objective of this research paper is plant species classification based on features of leaf. The organization of this paper...
