Visual feature extraction for lunar surface images

2012 5th International Congress on Image and Signal Processing, 2012
Visual feature extraction is foundation of lunar surface topography reconstruction. The paper studies visual feature extraction for lunar surface images, and then offers the visual feature extraction algorithm for lunar surface images. The experimental results show that the algorithm has good adaptability to illumination change, scale change and ...

Coordinates of lunar features

Icarus, 1965
Abstract The Aeronautical Chart and Information Center is producing a series of one to one million scale charts over the visible disk of the Moon and charts of one to five hundred thousand in the central regions. Inadequacies of existing lunar control have necessitated the establishment of a horizontal and vertical control system to support this ...

Topographic Features of the Lunar Maria and Basins

Solar System Research, 2021
More than 70 topographic profiles of 34 large lunar maria and basins were constructed and studied in order to obtain quantitative values of the parameters that characterize these formations, to identify patterns and features of their relief. The dependence of the absolute height of the bottom and the depth of the basins on latitude, longitude, size and

Lunar Features and Lunar Problems

Geological Society of America Bulletin, 1961
The major features of the Moon (marcs, highlands, craters, fractures) are briefly reviewed to encourage geologists to participate in the solution of lunar problems—problems involving the interpretation of varied land forms, the rock types and their distribution, potential ore deposits, and lunar tectonics.

Atypical features of a lunar corona

Journal of Optics A: Pure and Applied Optics, 2006
The image of a lunar corona recorded in 1979 is examined in detail. It is noticed that the profile is non-circular, the width of the coloured ring is almost independent of the angular distance from the moon, and an outer structure of fine rings is appearing.

Absolute coordinates of Lunar features. III.

Icarus, 1968
Abstract Absolute coordinates for lunar features have been derived using the so-called stereoscopic method. Use of a large number of plates taken at widely separated librations contributes to reducing the errors which are inherent in most coordinate systems yet produced.

Feature Extraction from Lunar Images

2011
Automatic feature identification from orbital imagery would be of wide use in planetary science. For geo scientific applications, automatic shape-based feature detection offers a fast and non-subjective means of identifying geological structures within data.

The main features of the geochemistry of lunar rocks

Physics and Chemistry of the Earth, 1979
Abstract Statistical cluster analysis of 635 individual bulk chemical compositions of lunar rocks distinguishes three major chemical groups which correspond respectively to highland rocks, high titanium mare basalts and mare basalts with moderate titanium contents.

Drawing Lunar Features

2000
Why go to the trouble of drawing lunar features? First, the exercise will force you to sharpen your visual observing skills. Later in this chapter there is a checklist that will help you to better describe what you are seeing. This exercise will also give you a chance to apply what we’ve learned about lunar geology. Second, drawings are the best way of

Lunar Impact Features

2009
The Moon is an airless body, devoid of the atmosphere that Earth has to protect it from the impacts of meteoroids. In the case of the Earth, the atmosphere shields the ground from all but the larger (and much rarer) meteoroid collisions. We see the collision between the meteoroid and the atmosphere as a “falling” or “shooting” star, sometimes leaving a
