Abstract :
A new method for the determination of adaptive palettes of color images with a variation of Kohonen (1984) networks, for the purposes of image storage and display, is presented. New neighborhood relationships in one and three dimensions are defined among neurons and the scope of these binds is also extended. The presented method is compared with popular palette selection algorithms, the resulting quality, provided network convergence, is competitive with the other methods, both for natural color and graphic images. Additionally, the resulting palettes show interesting topological relationships among colors
