Feature Extraction from Lunar Images
2011Automatic 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.

Lunar Features and Lunar Problems
Geological Society of America Bulletin, 1961The 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, 2006The 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.

Topographic Features of the Lunar Maria and Basins
Solar System Research, 2021More 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

Absolute coordinates of Lunar features. III.
Icarus, 1968Abstract 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.

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

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

Eclipse calculations of lunar features
Vistas in Astronomy, 1972Abstract Measurements of the times when lunar features (especially prominent craters) enter and leave the umbra during an eclipse of the Moon are important in evaluating the enlargement of the observed umbra over the size predicted geometrically. It may be useful to prepare prediction times of these crater entrances and exits.

Visual feature extraction for lunar surface images
2012 5th International Congress on Image and Signal Processing, 2012Visual 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 ...
