Example plots of the automatically detected flowers in the multispectral images (composited from the blue, red, and green band) and manually identified flowers in the color images.

In the multispectral images (top image in each panel), the magenta lines indicate detected flowers. In the color images (bottom image in each panel), the yellow circles indicate detected flowers and the yellow squares indicate undetected flowers in multispectral images. A) All the flowers in the color image were detected in the multispectral image. B) The flower inside the canopy was not detected in the multispectral image. C) Spots with high specular reflectance from the leaves were misclassified as flowers in multispectral images while the color images showed no flowers. D) Most of the flowers in the color image were detected in the multispectral image. Two partly hidden flowers and one flower inside the canopy were not detected in the multispectral image.
