AUTOMATIC DETECTION OF CLOUDS AND SHADOWS USING HIGH RESOLUTION SATELLITE IMAGE TIME SERIES
Clouds Shadows Landsat-8 Pléiades-HR Time Series Image Sequences
2016/7/27
Detecting clouds and their shadows is one of the primaries steps to perform when processing satellite images because they may alter the quality of some products such as large-area orthomosaics. The ma...
Efficient Image-Based Methods for Rendering Soft Shadows
Shadows Raytracing Image-Based Rendering
2016/5/24
We present two efficient image-based approaches for computation
and display of high-quality soft shadows from area light sources.
Our methods are related to shadow maps and provide the associated
b...
This paper addresses the problem of efficiently calculating shadows from environment maps
in the context of ray-tracing. Since accurate rendering of shadows from environment maps
requires hundreds o...
