Colour constancy as measured by least dissimilar matching.
Although asymmetric colour matching has been widely used in experiments on colour constancy, an exact colour match between objects lit by different chromatic lights is impossible to achieve. We used a modification of this technique, instructing our observers to establish the least dissimilar pair of differently illuminated coloured papers. The stimulus display consisted of two identical sets o...
متن کاملColour Constancy as Counterfactual
In this paper I argue that two standard characterizations of colour constancy are inadequate to the phenomenon. This inadequacy matters, since, I contend, philosophical appeals to colour constancy as a way of motivating illumination-independent conceptions of colour turn crucially on the shortcomings of these characterizations. After critically reviewing the standard characterizations, I provid...
متن کاملRelaxed Grey-World: Computational Colour Constancy by Surface Matching
In this paper we present a new approach to computational colour constancy problem based on the process of surface matching. Classical colour constancy methods do not usually rely on this important source of information and they often use only partial information in the images. Our proposal is to introduce the use of a set of canonical surfaces and its matching versus the content of the image us...
متن کاملColour constancy
What is colour constancy? Colour constancy is the tendency of objects to appear the same colour even under changing illumination. A yellow banana appears yellow whether you see it in the tungsten light of the kitchen or in sunlight outdoors. Under these different conditions, the banana reflects very different light spectra to your eyes, but you see instead its unchanging material properties. Th...
متن کاملFast Least Square Matching
Least square matching (LSM) is one of the most accurate image matching methods in photogrammetry and remote sensing. The main disadvantage of the LSM is its high computational complexity due to large size of observation equations. To address this problem, in this paper a novel method, called fast least square matching (FLSM) is being presented. The main idea of the proposed FLSM is decreasing t...
