The proposed spatial domain watermarking system is based on fuzzy logic and was designed with the intent of embedding watermark features such that they are undetectable to the human visual system. The objective is to manipulate the host image to a maximum that is below the threshold of detection using as a basis the texture and contrast surrounding the insertion subimage. To achieve this objective, the development and design of the watermarking scheme targets three of the five perceptual holes of the human visual system. The resulting watermarking scheme was evaluated using image processing techniques typical of an accidental attack process. The evaluation of the embedded watermark was subjected to a limited sample of human visual system observers. The watermarking scheme demonstrated excellent resiliency to image compression and ability to be implemented in images over a varied range of spectral characteristics.
