Bio-activity assessment of fruits using Generalized Difference and Parameterized Fujii method

Abstract

In this research work, both qualitative and quantitative measurement of biospeckle activity of three Indian fruits namely apple, pear and tomato have been carried out using Generalized Difference and Parameterized Fujii methods. Different activity area of the fruits can be easily visualized through the spectral maps. The variation of activity level of the fruits during shelf life storage has been studied through activity graphs. Comparative studies of activities of all the fruits are also presented and relatively high activity was found in apple compared to pear and tomato.
