EVALUATING REGIONS FOR DIGITAL WATERMARKING WITH PIXEL IMPACT FACTOR AND QUANTIZATION IN SPATIAL DOMAIN


Abstract

In this article I propose a novel usage of Pixel Impact Factor model to estimate regions for embedding digital watermark in image. Watermarking is performed in spatial domain, with usage of quantization methods. Using different quantization levels allow me to introduce relationship of Pixel Impact Factor and watermark capacity.
