WebJul 8, 2016 · Photometric Stereo is a popular method for 3D reconstruction from images due to its high level of details handling. However, when it is used in a scattering medium such as lakes and oceans, the recovery result will be negatively impacted by the light absorption, light scattering and the impurities in the water. In this paper, we present a new method to … WebCiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Photometric stereo is widely used for 3D reconstruction. However, its use in scattering media such as water, biolog-ical tissue and fog has been limited until now, because of forward scattered light from both the source and object, as well as light scattered back from the medium …

WebPhotometric stereo is widely used for 3D reconstruction. However, its use in scattering media such as water, biological tissue and fog has been limited until now, because of forward scattered light from both the source and object, as well as light scattered back from the medium (backscatter). WebApr 24, 2013 · We have presented an empirical study on the effects of translucency on photometric stereo. We have shown that multiple scattering has a blurring effect on the photometric normals, resulting in a less detailed shape characterization. We have shown that the relative size of mean free path versus geometrical feature size is the primary … trusted data format schema
