Classification of Cactus Disease Based on Infrared Wavelength Image Processing

Abstract

Cactus is one of the important cash crops of Thailand. Due to relatively easy to maintain, it has widely gained a lot of popularity in the field of ornamental plants. Cactus plants with soft rot is the crucial disease, since it does not indicate or effect to the appearance of the plant. This paper presents an application to analyze the cactus disease using infrared wavelength image processing. Normalized Difference Vegetation Index (NDVI) and OpenCV algorithm are utilized to determine the health of cactus plant. The overall application is operated on a Raspberry Pi with No InfraRed (NoIR) camera. The results show a capability of soft-rot detection in a group of cacti with a single image. This application offers a cost-effective plant health monitoring system for better production.
