Literature review of image features and classifiers used in leaf based plant recognition through image analysis approach

Plants play an important role in Earth's ecology by providing sustenance, shelter and maintaining a healthy atmosphere. Some of these plants have important medicinal properties. Automatic recognition of plant leaf is a challenging problem in the area of computer vision. An efficient Ayurvedic plant leaf recognition system will beneficial to many sectors of society which include medicinal field botanic research etc. With the help of image processing and pattern recognition, we can easily recognize the leaf images. This paper gives a survey on different leaf recognition methods and classifications. Plant leaf classification is a technique where leaf is classified based on its different features.
