디포커스와 디스패리티 좌표 변화량의 관계 연구 및 활용을 통한 스테레오 매칭의 정확도 향상

MasterIntegrating the shape from stereo and the shape from defocus/focus could enhance depth rendition. However, combining the two methods with different depth results is a very difficult problem. As an alternative, combining the disparity and blur before depth estimation may yield better rendition. In this context, this paper suggests a geometric relationship between the disparity and blur in rectified images. The derived relationship, called {\em differential stereo-defocus equation}, makes it possible to closely couple the stereo and blur in image planes.To check the differential stereo-defocus equation, we tested stereo matching which is constrained heavily by blur information. As can be expected from the equation, this approach can resolve the uncertainties in depth where the object surface has some slope over the image plane

학위논문(박사) - 한국과학기술원 : 화학과, 2010.2, [ xi, 96 p. ]Covalent Functionalization of Epitaxial Graphene by Azidotrimethylsilane Chemically modified epitaxial graphene (EG) by azidotrimethylsilane (ATS) was investigated using highresolution photoemission spectroscopy (HRPES). Through the spectral analysis, we clearly confirmed that EG is modified by thermally generated nitrene radicals and found that the bonding nature between the nitrene radicals and EG is covalent. As we observe bonding nature of N 1s peaks, we found that two distinct N peaks can be clearly distinguished in the spectra. Using a covalently bound stretched graphene (CSG) model, we elucidated that nitrene radicals adsorb on the graphene layer at two different adsorption sites. Moreover, we were able to control the band gap of EG using valence band spectra as we change the amount of the dosing of nitrene. Chemical Doping of Epitaxial Graphene by Organic Free Radicals Chemical doping of epitaxial graphene (EG) by organic free radicals (4-amino-2,2,6,6-tetramethyl-1-piperridinyloxy; 4-amino-TEMPO) was investigated using scanning tunneling microscopy (STM), scanning tunneling spectroscopy (STS), and high resolution photoemission spectroscopy (HRPES). STM images revealed that the empty density of states near the adsorption site significantly decreased as a result of radical doping. STS indicated that 4-amino-TEMPO radicals acted as n-type dopants on both monolayer and bilayer graphene. The radicals adsorbed onto EG through the nitroxide groups, leaving the amine group unreacted, which was confirmed by the binding energies of N 1s and O 1s core-level spectra. Furthermore, the measured work function changes verified that increased adsorption of the radicals on EG showed n-type doping characteristics. Adsorption Structures of Co on Si(100) The adsorption of Co on Si(100) at room temperature was studied using scanning tunneling microscope (STM).
