Many-core processor architecture has become the most promising computer architecture. However, how to utilize the extra system performance for real applications such as video encoding is still challenging. This dissertation investigates architecture design, physical implementation and performance evaluation of a fine-grained many-core processor for advanced video coding with a focus on intercon...

This paper addresses a novel video summarization procedure that produces a dynamic (video) abstract of the original video sequence. To remain temporal characteristic in the video abstract, a newly time-oriented feature is introduced. The approach relies on time instances, frame rate of the original video sequence and display speed of the video summary to select frames for a video abstract. This...

After 4K, 8K UHD resolution can be considered the new challenge for film, visualization and television. Due to the dimension of 8K image, the remote micro and macro images are considered appropriate for visualization with scientific and educational purposes. This article describes the implementation of the 8K video plug-in to play UHD videos into the SAGE, a collaborative environment for the ad...

In this paper we study the power of a model of tile self-assembly in which individual tiles of the system have the ability to turn on or off glue types based on the bonding of other glues on the given tile. This work is motivated by the desire for a system that can effect recursive self assembly, and is guided by the consideration of a DNA origami implementation of four-sided tiles which have a...

Seeing and describing real and imaginary three-dimensional scenes from the observer’s viewpoint is an intuitive activity for non-impaired people, but it is difficult for congenitally blind people, once it involves abstract concepts for them, such as: perspective, depth planes, occlusion, etc. This paper discusses the problem related to understanding three-dimensional concepts by blind people an...

The aim of this study was to evaluate the accuracy of some commonly used cephalometric landmarks of monitor-displayed images with and without image emboss enhancement. The following null hypothesis was tested: there is no improvement in landmark detection accuracy between monitor-displayed images, with and without image embossing enhancement. Forty lateral cephalometric radiographs, taken from ...

In this paper we present an MPEG-4 compliant system for viewing 360° high-resolution spherical panoramic images and videos. The system allows user navigation within an MPEG-4 3D scene description. Here, two different scene geometries were implemented: One consisting of a spherical geometry around the viewpoint and the other having a cylindrical geometry with associated texture patches each. The...
