Methods of Color Images Procession for Further Identification of the Object

The offered paper deals with the problems of color images preliminary procession. Among these are: interference control (local ones and noise) and extraction of the object from the background on the stage preceding the process of contours extraction. It was considered for a long time that execution of smoothing in segmentation through the boundary extraction is inadmissible, but the described methods and the obtained results evidence about expedience of using the noise control methods.

3D Environment for Virtual Collections

This paper describes a framework for building virtual collections of several digital objects and presenting them in an interactive 3D environment, rendered in a web browser. Using that environment, the website visitor can examine a given collection from a first-person perspective by walking around and inspecting each object in detail by viewing it from any angle. The rendering and visualization of the models is done solely by the web browser with the use of HTML5 and the Three.js JavaScript library, without any additional requirements.

Interactive Visualization of the Building of University of Economics – Varna via 3D Modeling

The object of this paper is presenting the University of Economics – Varna, using a 3D model with 3Ds MAX. Created in 1920, May 14, University of Economics - Varna is a cultural institution with a place and style of its own. With the emergence of the three-dimensional modeling we entered a new stage of the evolution of computer graphics. The main target is to preserve the historical vision, to demonstrate forward-thinking and using of future-oriented approaches.
