Frequency of metamerism in natural scenes.
Estimates of the frequency of metameric surfaces, which appear the same to the eye under one illuminant but different under another, were obtained from 50 hyperspectral images of natural scenes. The degree of metamerism was specified with respect to a color-difference measure after allowing for full chromatic adaptation. The relative frequency of metameric pairs of surfaces, expressed as a prop...
متن کاملIncidence of Metamerism in Natural Scenes
Estimates of the incidence of metameric surfaces, defined as having different spectral reflectances but appearing the same under a given light, were obtained from 40 hyperspectral images of natural scenes. The degree of metamerism was specified with respect to a color-difference metric after allowing for full chromatic adaptation to the scene. Although the proportion of pairs of surfaces in an ...

متن کاملPredicting frequency of metamerism in natural scenes by entropy of colors.
Estimating the frequency of metameric surfaces in natural scenes usually requires many comparisons of surface colors to determine which are visually indistinguishable under one light but distinguishable-by a certain criterion degree-under another. The aim here was to test the predictive power of a simpler approach to estimation based on the entropy of colors. In simulations with 50 hyperspectra...
متن کاملPlant Classification in Images of Natural Scenes Using Segmentations Fusion
This paper presents a novel approach to automatic classifying and identifying of tree leaves using image segmentation fusion. With the development of mobile devices and remote access, automatic plant identification in images taken in natural scenes has received much attention. Image segmentation plays a key role in most plant identification methods, especially in complex background images. Wher...
