Different from traditional algorithms, the material modeling method utilizing luma Y in YUV color space has been developed in this paper. Our method, which interactively acquires material appearance from a single image, includes four main steps: removing highlight, recovering normal based on luma Y, estimating diffuse coefficient, setting glossiness and specular coefficient interactively. The experiment...
Passive radar has recently received attention due to its advantages like low cost, covert operation, and difficulty of jamming. With cognition ability added in, passive radar's performance can improve for its adaptability to the environment. In this paper, multi-illuminator compatible cognitive passive radar, which aims at future complex electromagnetic environment and best potential illuminators...
The application of multi-media in teaching attracts more and more educators' attention, but many problems of multi-media teaching and learning have still existed in many county-level high schools in Hebei province, and the concerning degree about this is relatively small. Therefore, this paper will use questionnaires and visits as the research methods to collect all aspects of information about multi-media...
Patents are the manifest output of industry's R&D effort. This paper explores the development of six industries in China, including Chemical (excluding Drugs), Computers and Communications, Drugs and Medical, Electrical and Electronics (E&E), Mechanical, and Others. The results showed that the number of U. S. granted utility patents in China as well as their shares in the world had increased...
A group of prototype integrated circuits are presented for a wireless neural recording micro-system. An inductive link was built for transcutaneous wireless power transfer and data transmission. Power and data were transmitted by a pair of coils on a same carrier frequency. The integrated receiver circuitry was composed of a full-wave bridge rectifier, a voltage regulator, a date recovery circuit,...
