High Dynamic Range Imaging Of Natural Scenes

Alternatively our method can take a set of noisy images of dynamic scenes with the same short exposures and generate a clean denoised image that are of a high quality.

High dynamic range imaging of natural scenes. Wandell stanford university stanford california. A category of existing techniques first register the input images to a reference image and then merge the aligned images into an hdr image. Citeseerx document details isaac councill lee giles pradeep teregowda.

This paper describes. The algorithm takes a set of low dynamic range ldr images of dynamic scenes with different exposures as the input and outputs a high dynamic range hdr image. Standard techniques allow differentiation only within a certain range of brightness.

High dynamic range imaging of natural scenes feng xiao jeffrey m. Producing a high dynamic range hdr image from a set of images with different exposures is a challenging process for dynamic scenes. The ability to capture and render high dynamic range scenes limits the quality of current consumer and professional digital cameras.

Outside this range no features are visible because. First we used an acquisition system to capture high dynamic range natural scenes for characterization of the input requirements. We conducted a systematic study of the high dynamic range imaging pipeline.

High dynamic range imaging hdri is a technique used in photographic imaging and films and in ray traced computer generated imaging to reproduce a greater range of luminosity than what is possible with standard digital imaging or photographic techniques. We built a device capable of displaying complex image data far beyond the limit of traditional display devices.
