Nowadays, 3D graphical models have become commonplace in most computer graphics related industries. The accuracy and realism of these 3D graphics are achieved by fine geometric details which present challenges in rendering performance; transmission bandwidth; and storage capacities. All these motivate a need for compressing geometric data. In this paper, I talk about two compression techniques ...

Texture mapping has traditionally added visual realism to computer graphics images. Modern graphic boards reserve more space for image textures that are mapped in real time on 3D meshes. Outside the graphic accelerators texture images are stored in popular compressed formats that are not designed to meet real-time texture decompression requirements. In the paper we forward an alternative techni...

The purpose of this paper is three fold. First, the major theoretical pattern relationships of TV and/or FM transmitting antennas are dealt with. Secend, the computer calculation method and designing of such patterns using the given relationships. And third, a method in which a computer graphic system can be used to design such antennas for a specific pattern is introduced and its results are p...

R esum e: The ability to merge a real video image (RVI) with a computer-generated image (CGI) enhances the usefulness of both. To go beyond "cut and paste" and chroma-keying, and merge the two images successfully, one must solve the problems of common viewing parameters, common visibility and common illumination. The result can be dubbed Computer Augmented Reality (CAR). The solution needs cont...

abstraction shigeo fokuada is one of the geniuses of contemporary graphic designers of japan. he was born in tokyo in 1932. after finishing his studies in national university of fine arts & music (1956), he worked in many fields of professional graphic design and his poster designs gained world reputation. he as a representative of avant-garde graphic design, with increasing international atten...

This is the second part of an article on preparing images for medical publication. The first part dealt with optimal capture and export of pixel-based medical images. This part will deal with post-processing and editing of such images using specific software tools, and with the use of graphics illustration and charting software applications for creation of medical illustrations and charts. In t...

Photorealistic rendering methods have been at the centre of much computer graphic research and remain in that position to date. The aim of photorealism is to produce computer graphic images that cannot be distinguished from photographs. Such methods have produced impressive results, and in some cases the aim has been met. However, photorealism is not always a desirable goal, sometimes a hand-dr...

mCT In this paper, we propose an efficient algorithm which recognizes the mixed document consisting of the Korean/alphanumeric texts and graphic images. In the preprocessing step. we separate graphic image parts from the text parts by considering chain codes of cmected components. In the recognition step of the Korean/alphanumeric characters. we recognize the characters hierarchically using sev...
