- Evaluation of Postharvest Senescence of Broccoli via Hyperspectral Imaging

Visualization of HSI analysis of testing samples on days 1, 5, and 12, (a, c-d) for SPICE and (b, e-f) for MI-ACE. (a) Estimated endmembers using the SPICE methods on spectral images of broccoli florets. “EM” is an abbreviation of endmember. (b) Estimated discriminative target and background signature using the MIACE methods. (c) Abundance map of estimated endmembers for testing samples on day 1, day 5, and day 12. (d) Histogram of abundance value. The legend of x-axis and y-axis are the abundance value and their proportion, respectively. (e) Confidence map of target detected by MI-ACE for testing samples on day 1, day 5, and day 12. (f) Histogram of confidence value. The legend of x-axis and y-axis are the confidence value and their proportion, respectively.
