Irradiance Restoration Based Shadow Compensation Approach for High Resolution Multispectral Satellite Remote Sensing Images [PDF]
Sensors, 2020 Numerous applications are hindered by shadows in high resolution satellite remote sensing images, like image classification, target recognition and change detection. In order to improve remote sensing image utilization, significant importance appears for

Shadow Detection and Compensation From Remote Sensing Images Under Complex Urban Conditions
Remote Sensing, 2021 Due to the block of high-rise objects and the influence of the sun’s altitude and azimuth, shadows are inevitably formed in remote sensing images particularly in urban areas, which causes missing information in the shadow region.

Applied Sciences (Switzerland), 2023 As clouds of different thicknesses block sunlight, large areas of cloud shadows with varying brightness can appear on the ground. Cloud shadows in high-resolution remote sensing images lead to uneven loss of image feature information.

Applied Sciences (Switzerland), 2020 Current automatic shadow compensation methods often suffer because their contrast improvement processes are not self-adaptive and, consequently, the results they produce do not adequately represent the real objects.

A Leaf-Colour- and Shadow-Structure-Guided Method for Correcting Wheat Canopy Reflectance [PDF]
SensorsVariation in illumination and canopy geometry can affect the comparability of RGB measurements acquired at different times of day. This study proposes a wheat canopy reflectance correction method guided by leaf-colour and shadow-structure features.
