From: AgriSPEC: A smartphone-based, compact biospeckle imager for assessing seed viability

Results obtained using Fujii's method are shown for (a) N = 25, b N = 50, results obtained using GD's method are shown for (c) N = 25 (d) N = (50); and those obtained using SAM algorithm are shown for (e) N = 25 (f) N = 50.
