The article proposes an approach to selecting a suitable graphic container from multiple images for a specific message. Searching for an optimal container requires an analysis that takes into account both the human perception of the image and the mat

This paper presents an approach in integrating polygons into a triangulation. The motivation behind this work is to find a way to overcome the lack of appropriate shape-preserving methods for modifying 2.5D triangle meshes. Widely used approaches for

The paper presents a novel steganographic algorithm. It is based on a least significant bit method and a chaotic random system. The designed scheme is realized by the Raspberry Pi hardware. It is proved that the novel algorithm shows good statistical

In this report we propose a new steganographic method that allows to be transmitted through social networks stego information. The basis of the method is pre-grouping and classifying a large number of graphical images based on the type of their histo

The triangle meshes are often used to approximate smooth or piecewise smooth surfaces. Improving the uniformity of the approximation error distribution is crucial for the mesh quality. In order to achieve such improvement it is often necessary to inc
