Research patterns and trends in classification of biotic and abiotic stress in plant leaf

Abstract

The reason of plant diseases could be the reason of diseases in different parts of a plant such leaf, root and stems; however leave is one of the most important institutes to be observed to identify and detect infection. This paper covers different factors which is the reason of abiotic and biotic stress in plants. Literature different techniques are proposed to identify and classify plant diseases based texture, shape and size of leaf image. Each and every technique utilized automated technologies such artificial image analysis efficiently. This paper summaries the study of different automated techniques, tools and computation method used to detect and categories plant diseases based on leaf image with their pros and cons. Here in the study, the disease identification and classification process is divided into different phases and studied about different tools, techniques and method used in all the phases of complete process with their pros and cons. With the help of discovery of set of aspect, we have highlighted several points which can be considered for future research direction. This review helps others to grab knowledge of automated applications and techniques used to detect plant diseases.
