Fig. 8From: Deep learning for image-based large-flowered chrysanthemum cultivar recognitionHeat maps of eight large-flowered chrysanthemum images. a Cultivars whose centre disc florets are visible and b cultivars whose centre disc florets are invisible. Eight cultivars of chrysanthemum are shown in i–viii. In each heat map, the warmer the pixel's colour, the more attention the model pays to it.
