Objective quality measures or measures of comparison are of great importance in the field of image processing. These measures serve as a tool to evaluate and to compare different algorithms designed to solve particular problems, such as noise reduction, deblurring, compression, ... Consequently these measures serve as a basis on which one algorithm is preferred to another. In [15, 16] we constructed several new fuzzy similarity measures for grey-scale images that outperform the classical measures of comparison, like Root Mean Square Error or Peak Signal to Noise Ratio, in the sense of image quality evaluation. In this chapter we investigate the usefulness of these similarity measures for the comparison of colour images. First of all, we discuss the component-based approach in three different colour spaces, namely the RGB, HSV and Lab colour spaces. And secondly, we discuss a vector-based approach using vector morphological operators. Both approaches are compared by means of several experiments.
