Definition

The Vora Value, ν, measures the recording accuracy of a set of color filters [1]. The definition of ν takes into account the viewing and recording illuminants and the target color space. The original definition is independent of the data set to be recorded, does not take into account recording noise, and is based on the Euclidean distance measure in the target color space.

Let \( \mathbf{V}=\left[{\mathbf{v}}_1{\mathbf{v}}_2 \dots {\mathbf{v}}_{\mathrm{s}}\right] \)
