Multi-Threshold Corner Detection and Region Matching Algorithm Based on Texture Classification

open access: yesIEEE Access, 2019
In order to address the unreasonable distributed corners in single threshold Harris detection and expensive computation cost incurred from image region matching performed by normalized cross correlation (NCC) algorithm, multi-threshold corner detection ...

Radiation Pattern Measurement in the Planar Coordinate

open access: yesIEEE Photonics Journal, 2019
A planar measurement approach is presented to obtain the radiation pattern, by which rotation operations can be removed or reduced for a source with narrow and divergent viewing angle, respectively.

Radiation Risks and Mitigation in Electronic Systems [PDF]

open access: yes, 2016
Electrical and electronic systems can be disturbed by radiation-induced effects. In some cases, radiation-induced effects are of a low probability and can be ignored; however, radiation effects must be considered when designing systems that have a high ...

High-Performance Deep SubMicron CMOS Technologies with Polycrystalline-SiGe Gates [PDF]

open access: yes, 2000
The use of polycrystalline SiGe as the gate material for deep submicron CMOS has been investigated. A complete compatibility to standard CMOS processing is demonstrated when polycrystalline Si is substituted with SiGe (for Ge fractions below 0.5) to form
