Comparison of Color Difference Equations

Advanced color difference equations still do not necessarily predict accurately the color differences for complex stimuli such as photographic images. The CIELAB color-difference formula has been used extensively for quality control in industry but its application is limited because CIELAB space is still far from being perceptually perfectly uniform. The consequence of this is that for equal perceptual color differences, the values of CIELAB color differences can vary by an order of magnitude. The aim of this work is to compare accuracy of three color difference equations that are recently used.
