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 ...

ACCURACY OF 3D RECONSTRUCTION IN AN ILLUMINATION DOME
Photogrammetry structure from motion 3D test object photometric stereo digital elevation model
2016/11/11
The accuracy of 3D surface reconstruction was compared from image sets of a Metric Test Object taken in an illumination dome by two methods: photometric stereo and improved structure-from-motion (SfM)...
MUTUAL COMPARATIVE FILTERING FOR CHANGE DETECTION IN VIDEOS WITH UNSTABLE ILLUMINATION CONDITIONS
Change detection moving object detection illumination changes mutual comparative filters
2016/7/27
In this paper we propose a new approach for change detection and moving objects detection in videos with unstable, abrupt illumination changes. This approach is based on mutual comparative filters and...
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...
An artificial tree/stand model combined with different illumination strategies for the retrieval of forest stand structural parameters
Artificial forest stands stand structure very high resolution radiative transfer
2015/9/2
A new method for the estimation of forest stand density (trees/ha), crown diameters (m) and crown closure (percentage
covered) using artificially generated reference imagery is presented. The method ...
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 ...
OCCLUSION, CLUTTER, AND ILLUMINATION INVARIANT OBJECT RECOGNITION
Computer Vision Real-Time Object Recognition
2015/3/24
An object recognition system for industrial inspection that recognizes objects under similarity transformations in real time is proposed.
It uses novel similarity measures that are inherently robust ...
Phase Correlation based Local Illumination-invariant Method for Multi-Tempro Remote Sensing Image Matching
Phase Correlation Terrain Image Matching Illumination Angle Change
2014/9/9
This paper aims at image matching under significantly different illumination conditions, especially illumination angle changes, without prior knowledge of lighting conditions. We investigated the illu...
RECONSTRUCTION OF SKY ILLUMINATION DOMES FROM GROUND-BASED PANORAMAS
Sky radiance illumination environment map terrestrial images
2014/4/28
The knowledge of the sky illumination is important for radiometric corrections and for computer graphics applications such as relighting or augmented reality. We propose an approach to compute environ...
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...
