Intensity based algorithms for biospeckle analysis

In this paper, two algorithms, one is an Alternative Fujii method and other is parameterized form of temporal difference (PTD) method are presented. Experimental results for both the methods using sequential biospeckle images of fresh apple have been presented and compared with the results obtained using that of Generalized Difference (GD) and Parameterized Fujii. Good agreements are seen for particular values of parameters.
