The Use of Separated Reflection Components in Estimating Geometrical Parameters of Curved Surface Elements
نویسندگان
چکیده
Iterative least-squares estimation requires acciirate reflectance models to retrieve geometrical pammeters of curved surface elements from an image projection. W e investigate the use of .separating the diffuse (body) reflection from the specular (surface) reflection being re8ponsible for image highlights. Experzments show that the (smooth) daffuse component yields the best convergence properties, while the (sharp) specular component can contribute to the improvement of the noise insensitivity.

Sensitivity Analysis of Frequency Response of Atomic Force Microscopy in Liquid Environment on Cantilever's Geometrical Parameters
In this paper, the non-linear dynamic response of rectangular atomic force microscopy in tapping mode is considered. The effect of cantilever’s geometrical parameters (e.g., cantilever length, width, thickness, tip length and the angle between the cantilever and the sample's surface in liquid environment has been studied by taking into account the interaction forces. Results indicate that the r...
متن کاملA Radiometric Noise Model for Estimating Geometrical Parameters of 3-D Bodies from Multispectral Images
Camera images can be used to measure the geometry of man-made objects. An iterative weighted least-squares estimator with knowledge of imaging and reflection models retrieves the geometrical parameters of objects in a 3-D scene from 2-D image projections. We investigate the use of multispectral imagery which allows us to separate diffuse and specular reflection before estimating geometry. We bu...

A large number of civil registries are available as analog maps that require georeferencing. Besides the quality of the analog maps and control points, the algorithm used for georeferencing also affects the accuracy of the map and the carried out geometrical calculations which indicates the need to study modern Georeferencing Methods. This requires the adoption of georeferencing optimization mo...
متن کاملEstimating Light Position and Surface Reflectance from Specular Reflection under Perspective Projection
In this paper, we propose a new method for estimating reflection properties of a real object surface from a single specular component image, as well as the light source position. Polarization is used for separating the diffuse and specular reflection components. Different from previous approaches, which heavily assumed both distant viewpoint and illuminant position, our method can work even und...

Introduction Understanding the spectral reflectance of different soils and other surface elements forms the basis for analyzing the process of interpreting remote sensing data. Spectral properties of the various phenomena of the Earth's surface are not constant and are changing, based on the complex time and space conditions. Determination of soil chemical properties using remote sensing techni...
