SHAPE AND ALBEDO FROM SHADING (SAfS) FOR PIXEL-LEVEL DEM GENERATION FROM MONOCULAR IMAGES CONSTRAINED BY LOW-RESOLUTION DEM
Moon DEM Shape and Albedo from Shading (SAfS) Monocular Image
2016/11/8
Lunar topographic information, e.g., lunar DEM (Digital Elevation Model), is very important for lunar exploration missions and scientific research. Lunar DEMs are typically generated from photogrammet...
Towards optimal relief representation from Mars imagery by combination of DEM and shape-from-shading
Mars imagery combination DEM shape-from-shading
2016/5/20
Described are experimental results of a first approach towards optimal shaded relief representation of the surface of Mars derived from Viking Orbiter digital imagery. The complex problem addresses ho...

2016/3/17
Relief shading maps have become a popular and useful means for representing topography in a natural, aesthetic, and intuitive way.In this paper, a comparison among the applications in producingrelief ...
IMAGE-BASED 3D SURFACE RECONSTRUCTION BY COMBINATION OF SPARSE DEPTH DATA WITH SHAPE FROM SHADING AND POLARISATION
Industry Metrology Application Polarization Three-dimensional Reconstruction Close Range Photogrammetry
2015/8/31
In this contribution we describe an image-based framework for 3D surface reconstruction by a combined analysis of reflectance,polarisation, and sparse depth data. An error functional consisting of sev...

Industry Metrology Application Polarization Three-dimensional Reconstruction Close Range Photogrammetry
2015/8/28
In this contribution we describe an image-based framework for 3D surface reconstruction by a combined analysis of reflectance,polarisation, and sparse depth data. An error functional consisting of sev...
Shape from Shading is one of the methods used for shape recovery which exploits the fact that surface patches, having different
inclination relative to a light source are imaged with different bright...

Multi-image Shape-from-shading: Derivation of Planetary Digital Terrain Models Using Clementine Images
High-resolution DTM extraterrestrial surfaces reconstruction method
2015/7/8
In many cases, the derivation of high-resolution digital terrain models (DTMs) from planetary surfaces using only conventional
digital image matching is a problem. The matching methods need at least ...
