1 p, 46.7 KB Colour constancy in natural images through colour naming and sensor sharpening / Vázquez Corral, Javier
Colour is derived from three physical properties: incident light, object reflectance and sensor sensitivities. Incident light varies under natural conditions; hence, recovering scene illuminant is an important issue in computational colour. [...]
