title = "A shadow information recovery technology in 3D visualization of urban remote sensing images",
abstract = "Using high-resolution remote sensing images for 3D modeling of urban buildings is widely common. However, the processing of shadows plays a vital role in 3D visualization, and the shadows in urban areas is more complicated. Hence, the research on shadow restoration is essential. The paper introduces the reconstructed DEM model data as prior knowledge, uses the characteristics of sunlight shadows and shadows in different channels for shadow detection, and finally proposes a shadow compensation method based on the Wallis filter principle and improved logarithmic transformation combined with shadow local enhancement, to compensate the detected shadows.",
