Polarimetry and Shape from Shading
نویسندگان
چکیده
In this paper the effects of polarimetry on the Synthetic Aperture Radar (SAR) shape-from-shading (SfS) technique developed by the authors are analysed and discussed. In particular, the validity of some hypotheses, on which the method is based, is investigated for the different polarization channels and their influence on the accuracy of the proposed SfS technique is discussed. The paper concludes providing some suggestions for polarization exploitation within the proposed technique, in order to improve overall performances.

متن کاملShape-from-shading is independent of visual attention and may be a 'texton'.
Shading was used to generate the appearance of an obliquely illuminated surface with spherical indentations and protrusions. The "pop-out" of an apparent indentation among numerous apparent protrusions served as a psychophysical assay for shape-from-shading. Detectability of the pop-out varied with the direction of apparent illumination, a finding which is characteristic for shape-from-shading ...
متن کاملA Divide-and-conquer Strategy in Recovering Surface Shape of Book from Shading
A divide-and-conquer strategy in shape from shading is proposed for recovering book surface on fully perspective condition. It is shown that unique shape can be recovered despite of more unknowns than shade images by dividing original implicit SFS problem into explicit ones. Using invariance of shading, a transformed shading equation and a recurrence relation is derived for depth recovery. Whol...
متن کاملShape from Shading through Shape Evolution
In this paper, we address the shape-from-shading problem by training deep networks with synthetic images. Unlike conventional approaches that combine deep learning and synthetic imagery, we propose an approach that does not need any external shape dataset to render synthetic images. Our approach consists of two synergistic processes: the evolution of complex shapes from simple primitives, and t...
متن کاملShape Reconstruction of Skin Surface from Shading Images Using Simulated Annealing
This paper describes about a new method for reconstructing a shape of a skin surface replica from three shading images taken with three di erent lightings. Since the shading images include shadows caused by surface height uctuation, the conventional photometric stereo method is not suitable for reconstructing its surface shape. In the proposed method, the evaluation function of the surface shap...
