Spatial Tone Mapping in High Dynamic Range Imaging

Spatial tone mapping is a critical technique in high dynamic range (HDR) imaging, aimed at rendering images that preserve detail across a wide luminance range. This process involves adjusting the brightness and contrast of HDR images for display on standard devices, ensuring that both dark shadows and bright highlights are visible. Innovative algorithms can enhance the visual quality and realism of HDR images by preserving spatial relationships and important features. This paper discusses various spatial tone mapping methods, their effectiveness, and applications across different fields.
