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.

This paper deals with building 3D model of a mobile object based on one or more images obtaining from single CCD camera with fixed position. Some existing methods of analysis and measurements are applied and combined to obtain system for automatic generation of a 3D wired model suitable for application in adequate software packages.
