Good-looking green images

In this paper we present a novel perceptually-based algorithm for color quantization that produces images that consume less energy than conventionally quantized images when displayed on modern energy-adaptive displays. To evaluate the performance of the proposed algorithm, we performed a subjective study on a standard Kodak color image database. Experimental results indicate that the proposed algorithm is able to reduce the energy consumption by 4.25% on average, while achieving the same or better subjective image quality as conventional color quantization.
