Characterization of Leaf and Comparison with Optical and Millimetre Wave for Identification
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 3, Issue 11
Abstract
By optical photography, we can identify various leafs and vegetation canopies by their variations in color, variations in size and shape, and other optically visible parameters.If we see the same leaf and vegetation canopy with the help of millimetre waves by the techniques of imaging, transmisittivity, reflectivity, emissivity, we can get more information regarding the plant and the leaf growth, leaf constituent’s material such as water, phosphate, nitrate, magnesium, potassium and many other material present in the leaf or vegetation canopy.In brief, with the help of millimetre wave and using various above mentioned techniques we can get more information which otherwise not visible apparently. Within the millimetre wave range, we can use 22.235 GHz, 31.4 GHz, 35 GHz, 54GHz, 94 GHz frequencies. This multi frequency within millimetre wave can give us the data for proper imaging. As we know, in a present day scenario, imaging means outward photography by optical waves in optical wavelength, in infrared wavelength (for thermal photography) and microwavemillimetre wave imaging of the inner constituent material. With the appropriate software we can plot various image processing mapping for better understanding. Some of our observations with image processing approach are given below to invite more inputs from other researchers.
