Recovering Depth Map from Enhanced Image Gradients

open access: yesProcedia Computer Science, 2015
AbstractThis paper presents a new and efficient approach for recovering surface height from its image gradients. In order to compensate noise effect in image intensities, Gaussian filter is used to smooth the intensity values. Image gradient is calculated from the smoothen image by taking the central difference of intensity values.

Optical Coherence Tomography in Inflammatory and Neoplastic Lesions Deforming the Choroidal Profile

open access: yesDiagnostics, 2023
The choroid is the main part of the uvea, the vascular layer of the eye that lies between the retina and the sclera. The high vascular component of the choroid makes this structure susceptible to inflammation in multisystemic diseases, as well as the ...

Depth Imaging Enhancement Using Reverse Time Migration

open access: yesIOP Conference Series: Earth and Environmental Science, 2017
Imaging the subsurface with complex structures and steeply dipping salt boundaries is a challenging task in seismic exploration. Between two main categories of seismic migration, wavefield-continuation methods have been more successful than ray-based ones.
