Reducing object curvature and height variation effects in hyperspectral images

Not Accessible

Your library or personal account may give you access

Abstract

Curvature and height corrections were made on hyperspectral images in order to reduce intensity dependence on distance and inclination. The corrections were made by Lambertian cosine law and measured 3D surface of the sample. Image of homogeneous phantom appeared significantly more homogeneous after correction.
