In this paper, we consider a technique for watermarking in spatial domain, which is based on the spatial decomposition of the image in blocks and the pixel classification into homogeneous luminance zones. From the experimental results the quality of watermarked images, displayed on mobile phone, PDA and CRT screen are evaluated and thus high-resolution display is obtained, as the image quality is important factor in watermarking.
