Usgs High-resolution Topomapping of Mars with Mars Orbiter Camera Narrow-angle Images
We describe our initial experiences producing controlled digital elevation models (DEMs) of Mars with horizontal resolutions of ≤10 m and vertical precisions of ≤2 m. Such models are of intense interest at all phases of Mars exploration and scientific investigation, from the selection of safe landing sites to the quantitative analysis of the morphologic record of surface processes. Topomapping ...
متن کاملRemoving Shadows from Images
We attempt to recover a 2D chromaticity intrinsic variation of a single RGB image which is independent of lighting, without requiring any prior knowledge about the camera. The proposed algorithm aims to learn an invariant direction for projecting from 2D color space to the greyscale intrinsic image. We notice that along this direction, the entropy in the derived invariant image is minimized. Th...
متن کاملViscous flow features on the surface of Mars: Observations from high-resolution Mars Orbiter Camera (MOC) images
[1] A unique morphology suggestive of viscous flow of a meters-thick surface layer was identified in high-resolution (<10 m/pixel) Mars Orbiter Camera (MOC) images. A global survey of 13,000 MOC images resulted in the identification of 146 images exhibiting these viscous flow features. Slope angles derived from Mars Orbiter Laser Altimeter (MOLA) data, along with an experimentally derived flow ...
متن کاملObservation of the Martian Cryptic Region from Mars Orbiter Camera
Introduction: The distribution of the Martian south pole is not symmetric during the springtime retreat. On the opposite side of the residual cap a socalled cryptic region is found between latitudes 75 and 85 and longitude 150 W and 310 W [8]. A major puzzle about the cryptic region is that the albedo appears almost as dark as the bare ground but the surface temperature still remains cold. The ...
