Color difference based on CIE94 or CIE2000 standard

specifies additional aspects of the computation, such as the input color space and the CIE
standard, using one or more name-value pair arguments.`dE`

= imcolordiff(`I1`

,`I2`

,`Name,Value`

)

To calculate color differences following the CIE76 standard, use the

`deltaE`

function. This function is faster than the`imcolordiff`

function, but less precise.
