Red edge point detection for mulberry leaf

Abstract

Red Edge point (R E P) is very much related with chlorophyll foliar concentration and contents. Deep absorption of chlorophyll a and chlorophyll b affects the sudden change in region starting from 680 nm to 800 nm of green vegetation reflectance spectrum. Greenness area of the observation can be recognized by Red Edge Point. The Vegetation which is given by remote sensing methods consist of Red Edge Point in spectrum. REP also can be observed using lab or field experiments. In which canopy spectral reflectance were obtained with an A S D Field Spec PRO spectro radiometer that provides measurements in the spectral range starting from 350 nm to 2500 nm with 3 nm spectral resolutions and 1 nm sampling step. These experimental results can be used to identify different crops. Unhealthy crops can be found using remote sensing data. Spectro radiometer gives us refraction and reflection same as of remote sensing data. This can be possible if we can found Red Edge Point. Dryness of plants are detected using this technique. Current work in this paper consist of finding stress of mulberry, cotton and sugarcane plants estimating result using peak derivative, linear interpolation, linear extrapolation method. Finally result is compared using above all methods.
