Coding of 3D virtual objects with NURBS

With the advancement of computer graphics in the recent years, an increasing number of pictures, video and 3D content is generated by synthesis processing rather than acquired with capture devices such as cameras or scanners. Several techniques have been developed for compression of discrete (i.e. piece-wise planar) 3D models, in the form of 3D polygonal meshes. However, no important attempt ha...

Coding Principles for Virtual Acoustic Openings

Acoustic opening is a multichannel audio communications system. It consists of an array of microphones in the transmitting room and an array of loudspeakers in the receiving room. The goal is to provide listeners in the receiving room an impression that there is only an opening, or a window, on the wall between the two rooms. This can be done using a large number of audio channels and performin...

3D space coding using virtual object surface

In order to describe and transmit the entire visual data of a 3-D space, the authors have proposed the concept of the “3-D Space Coding.” We applied a DCT-based method to the data space in which light ray data was recorded. Our method could compress light ray data more effectively than the video coding method like MPEG2. This paper discusses the “3-D Space Coding” using the structural propertie...

A Virtual Retina for Studying Population Coding

At every level of the visual system - from retina to cortex - information is encoded in the activity of large populations of cells. The populations are not uniform, but contain many different types of cells, each with its own sensitivities to visual stimuli. Understanding the roles of the cell types and how they work together to form collective representations has been a long-standing goal. Thi...
