Fig. 4From: Utilization of computer vision and multispectral imaging techniques for classification of cowpea (Vigna unguiculata) seedsApplication of LDA model for discrimination between non-aged seeds and those seeds aged for 24, 48, 72 and 96 h. The first raw shows the original color images of the seeds and the second raw visualizes the classification results after applying the LDA model in every single pixel in the images.
