Abstract
- In real time watermarking applications robustness and computational complexity are playing very important role. In this paper we focus on new algorithm for inserting of watermark in digital still images. This algorithm is based on simple but efficient geometrical transformation of image and has fast embedding and extracting watermark pattern with acceptable robustness. Proposed method is illustrated on one example. It has been shown that it is possible to confirm existing of the watermark also in JPEG compressed image.
