Abstract: |
Differential
Evolution is an optimization technique that has been successfully employed in
various applications. In this paper we apply Differential Evolu- tion to the problem of generating an
optimal colour map for colour
quantised images. The choice of entries in the colour map is crucial for the resulting image quality as
it forms a look-up table for all pixels in the image. We show that Differential
Evolution can be effectively employed as a method for deriving the entries in
the map. In order to optimise the image quality our
Differential Evolution approach is combined with a local search method that
is guaranteed to find the local optimal colour map.
This hybrid approach is shown to outperform various commonly used colour quantisation algorithms
on a set of standard images. |
