2018年SPIE非成像光学会议（SPIE Nonimaging Optics:Efficient Design for Illumination and Solar Concentration XV）
2018年 SPIE 非成像光学 会议
2017/11/27
Many important optical subsystems are concerned with power transfer and brightness rather than with image fidelity. Nonimaging optics is a design approach that departs from the methods of traditional ...

Illumination Decomposition for Material Recoloring with Consistent Interreflections
Illumination Decomposition Consistent Interreflections
2016/5/24
Changing the color of an object is a basic image editing operation,
but a high quality result must also preserve natural shading. A common
approach is to first compute reflectance and illumination i...
Extraction and tracking of orientation coded features being robust against illumination changes
feature extraction tracking orientation code richness
2015/8/25
We present a feature extraction and tracking method which is based on pure rich texture analysis and has robustness under irregular conditions, such as illumination change, deformation of objects and ...
High-Efficiency Polarized Light Illumination System for Liquid-Crystal-Display Projectors
liquid crystal display illumination system projector polarization conversion shape conversion offset design
2011/11/30
We present a new optical system with two identical s- and p-polarized light paths for converting a random polarized beam into a linearly polarized one. The system also provides a uniform and rectangul...
Design of illumination and projection optics for projectors with single digital micromirror devices
2011/11/29
We present a new optical system design for a projector with a single digital micromirror device ~Texas Instruments Digital Micromirror Device! that improves on previous designs in terms of optical eff...
An integrated polarized light guide was designed and fabricated for use as a liquid-crystal backlight with emphasis on uniformity of the light and conversion of p-polarized to s-polarized light. Two d...
Efficient Polarized Backlight for Transflective Liquid Crystal Display Illumination
backlight polarization conversion birefringence transflective LCD
2011/11/25
A collimated backlight was designed for high-efficiency transflective liqud crystal display (LCD) illumination. Additionally, polarization separation was achieved by selective total internal reflectio...
Progress in high-responsivity vertical-illumination type Ge-on-Si photodetecor operating at λ ~1.55 μm
silicon detectors Optoelectronics Photodetectors
2011/5/26
We present a vertical-illumination-type 100% Ge-on-Si photodetector with the responsivity up to 0.93 A/W at λ~1.55 μm. The 10Gbps photoreceiver with a fabricated 60 μm-diameter device exhibits high se...
Illumination method for high resolution imaging at water surface
optical measurement optical instrumentation optical imaging
2010/9/16
Annularly distributed light is proposed to increase the spatial resolution when observing a water
surface. When light with an annular distribution is used to illuminate the entrance pupil of
an obje...
Active illumination and appearance model for face alignment
AIA alignment illumination face modeling sub-spaces active appearance
2010/7/31
Illumination conditions have an explicit effect on the performance of face recognition systems. In particular, varying the illumination upon the face imposes such complex effects that the identificati...
Illumination Transfer Using Homomorphic Wavelet Filtering and Its Application to Light-Insensitive Face Recognition
Homomorphic Wavelet Filtering Light-Insensitive Face Recognition
2008/12/31
In this paper, we propose a novel homomorphic wavelet filtering based illumination transfer technique to change the dominant lighting of one face image (source face image)to another face image (refere...
HSymmetric segment-based stereo matching of motion blurred images with illumination variations
motion blurred images illumination variations
2008/12/31
Most existing methods of stereo matching focus on dealing with clear image pairs. Consequently, there is a lack of approaches capable of handling degraded images captured under challenging real situat...
