Automated retinal shadow compensation of optical coherence tomography images [PDF]
We present an automated numerical method of compensating for retinal shadows in the choroid. In this method, signal extinction caused by retinal vessels is estimated by subtracting median A-scans obtained from beneath the retinal vessels and A-scans from the surrounding area. Adding the obtained offset vector to A-scans from beneath the retinal vessels

Enhanced Indoor Location Tracking Through Body Shadowing Compensation [PDF]
This paper presents a radio frequency (RF)-based location tracking system that improves its performance by eliminating the shadowing caused by the human body of the user being tracked. The presence of such a user will influence the RF signal paths between a body-worn node and the receiving nodes.

An in-depth analysis of hyperspectral target detection with shadow compensation via LiDAR
Abstract Shadowy areas present a big hindrance in target detection from HSI, as the reflectance data received from target materials is significantly diminished when measured from shadowy areas. In this work, we perform an in-depth analysis of hyperspectral target detection on targets in full illumination and in partial or full shadows; and analyze ...

A Review on Various Shadow Detection and Compensation Techniques in Remote Sensing Images
Remote sensing images provide a valuable source of information about the earth's surface. The presence of shadow can reduce the amount of information that can be extracted from these images.
