Linear Chromatic Adaptation Transform Based on Delaunay Triangulation

Table 2

Results of the Mann-Whitney U test comparing median PED errors of different CAT methods.

A positive value (1) at location (𝑖,𝑗) indicates that the median PED error of the methods 𝑖 is significantly lower than the median PED error of method 𝑗 at the 95% confidence level. A negative value (−1) indicates the opposite, and a zero (0) indicates that there is no significant difference between the two methods.
