Bors, A.G.,Hancock, E.R.,Wilson, R.C. - 《IEEE Transactions on Pattern Analysis & Machine Intelligence》 被引量: 102发表: 2003年 Terrain Analysis Using Radar Shape-from-Shading. This paper develops a maximum a posteriori (MAP) probability estimation framework for shape-from-shading (SFS)...
Secondly, the surface is recovered from needle map using a two-dimensional cellular automata system. An experimental assessment is provided for our methods on both real world images and synthetic images with known ground truth. The experiment results demonstrate this approach is practicable and has ...
The problem with texture shading by itself, however, is that it looks nothing like the terrain we are accustomed to seeing on maps, and the dark tones interfere with other map information, such as labels. A more practical use of texture shading is for mapmakers to merge it with shaded ...

This paper proposes a technique for creating a 3D terrain map from gray scale image. This technique is accomplished by using the principle of light and shadow in terms of azimuth, elevation angle and light path to locate the actual position of shadow on the image. The shading area is approxi...
It is shown how to use this constraint to recover a depth map from an image efficiently. A curious difference from the classical shape-from-shading problem is uncovered. When one assumes a point light source, the local geometric constraints of the shape-from-shading problem lie along the ...
If this element is omitted on a given paragraph, its value is determined by the setting previously set at any level of the style hierarchy (i.e. that previous setting remains unchanged). If this setting is never specified in the style hierarchy, then no paragraph shading shall be applied....
When I use the shading on a line (with double-spaced 0pt before and after) in MS Word, I see that the shading area exceeds more at the bottom of the line. However, this doesn't happen with single... debojitacharjee Copper Contributor ...
Shaded relief is a method for representing topography on maps in a natural, aesthetic, and intuitive manner. On this website you will find rules and guidelines for the design and production of shaded relief, an overview of its history, examples produced by professional relief artists, technical ...
