Nature, 1965 THE first reports from Mariner IV indicate that the planet Mars possesses a negligible magnetic field when compared with that of Earth. This is strong confirmation of the view that Mars has not developed a core. In a recent communication to Nature1 we suggested that a cyclical process which can be discerned in the Earth's history, and is responsible ...

Optimal surface relief reconstruction from both the photometric and the altimetric data [PDF]
Радиофизика и электроника, 2019 Subject and purpose. The paper discusses the extension of the photometric method for the surface relief retrieval from images in the optical and radar wavelengths ranges through the involving of the direct heights measurements by an altimeter onboard the

Relief Extraction From a Rough Stele Surface Using SVM-Based Relief Segment Selection
IEEE Access, 2021 Archaeological steles having a rough surface due to long periods of weathering make recognizing the inscription difficult. In this paper, we propose a machine learning-based method to extract reliefs for the inscription from a rough stele surface. Relief

Applied Sciences, 2021 It is challenging to extract reliefs from ancient steles due to their rough surfaces, which contain relief-like noise such as dents and scratches. In this paper, we propose a method to segment relief region from 3D scanned ancient stele by exploiting ...

Surface Relief Analysis for Illustrative Shading [PDF]
Computer Graphics Forum, 2012 AbstractIn this paper, we present an analysis technique that leverages the complexity found in detailed 3D models for illustrative shading purposes. Given a smooth base surface with relief, it locates relief features (concavities, convexities and inflections) around each surface point and at multiple scales, using cubic‐polynomial fitting.

Surface relief meter based on trinocular vision [PDF]
Fifth International Conference on Image Processing and its Applications, 1995 The concept for the relief meter being developed, appears to function well, when used with the artificial images. The described matching criterion leads to high matching percentages, and accurate results. The percentage of mismatches is reduced to practically zero for the tested scenes.
