Taxonomy of leaf disease detection and classification

Abstract

Gaining foods from plant is the most difficult task when plant suffers from diseases like fungal, bacterial, and virus. Leaf is the most affected part of plant diseases. Although farmers are proficient to detect leaf disease, if crops are spread in dense area, then this task is more difficult. Image processing provides an easy technique to detect leaf disease using symptoms. In this paper, we present various method such as background removal, enhancing, segmentation, feature extraction, and classification. Some leaf disease detection, grading, and classification are also discussed.
