Image Segmentation of UAV Fruit Tree Canopy in a Natural Illumination Environment
Agriculture, 2022 Obtaining canopy area, crown width, position, and other information from UAV aerial images and adjusting spray parameters in real-time according to this information is an important way to achieve precise pesticide application in orchards.

Enhanced Indoor Location Tracking Through Body Shadowing Compensation [PDF]
IEEE Sensors Journal, 2016 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.

One scan shadow compensation and visual enhancement of color images [PDF]
2009 16th IEEE International Conference on Image Processing (ICIP), 2009 The paper presents a new technique of efficient dynamic range compression and shadow compensation for still color images. The proposed method enhances low light areas while preserving the colors and details, without generating visual artifacts. The approach is based on recursive filtering and contrast stretching techniques, driven by statistical ...

An in-depth analysis of hyperspectral target detection with shadow compensation via LiDAR
Signal Processing: Image Communication, 2021 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 ...

Automated retinal shadow compensation of optical coherence tomography images [PDF]
Journal of Biomedical Optics, 2009 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

A Review on Various Shadow Detection and Compensation Techniques in Remote Sensing Images
Canadian Journal of Remote Sensing, 2017 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.
