This paper presents the color quantization of color document images by using a self-organizing map (SOM). The purpose of this research is to separate the text region from background using color quantization in complex color documents such as journal covers. We propose an inporoved algorithm that is a modifiied version of the Ong's SOM. We also propose to introduce the edge-preserving smoothing as preprocessing and the sub-sampling with local fractal dimension, that is suitable for reducing small regions which will occur at color quantization and for obtaining better results than conventional methods. |
