Fig. 4: Images of peanut seeds during the experiment.
From: AgriSPEC: A smartphone-based, compact biospeckle imager for assessing seed viability
a Speckle image captured using a developed prototype of viable peanut seeds and non-viable peanut seeds (bottom row). All seeds have undergone imbibition for timeT = 2 h. b RGB image of the same peanut seeds after being kept for germination for time T = 48 h. c GD output of viable and non-viable peanut seed samples at T = 2 h. d SAM output of peanut seed samples atT = 2 h.
