Investigation and Monitoring Systems for Powdery Mildew Disease in Sirugamani Variety of Betel Vine Plants Using Digital Image Processing Techniques

Abstract

Betel vine leaves are popularly known as Vetrilai in Tamil and also commonly known as Pan in Hindi. The biological name of betel vine is known as Piper betel. In this research paper, the powdery mildew disease is identified for sirugamani variety of betel vine leaves using digital image processing techniques by investigating the microscopic change in the color and appearance of the betel vine leaves. For statistical analysis, the digital images of healthy betel vine leaves and betel vine leaves infected by the powdery mildew disease from its first day to fifth day of infection are individually collected by a high-resolution digital camera. The red, green and blue color components of collected images are separated, and the mean, median and standard deviation values are calculated for all the three color components. Finally, the calculated values are stored in a database for healthy betel vine leaves and betel vine leaves infected by the powdery mildew disease for first five days after its identification. The statistical values of all the infected betel vine leaves for all the three color components are decreasing as the day of infection increases for all the betel vine leaves. These analyses help to identify the infection of the powdery mildew disease in the early stage of betel vine leaves.
