Localization and Estimation of Plant Disease Intensity for Aerial Image

Disease spreading in crops is a very important topic to work on. Knowing where and how severe the disease has spread in the field would help individuals to take effective counter measures to reduce or stop the spreading of the disease. In this paper image segmentation was performed on the aerial image of wheat crop on the basis of colour spaces to find out the where in the field the disease is present. The disease was shown by masking the affected area over a black background. The disease stem rust was focused on and the density of this particular disease was found out from the image itself using the mask image. The results also gave the estimation of the disease in percentage value so as to know what amount or how severe the disease has covered the crop field. Such calculation could also help to understand the pattern of spreading of the disease.
