High dynamic range imaging via robust multi-exposure image fusion

An image produced using the new method has more vivid color appearances and fewer artifacts in both static and dynamic situations. Credit: PolyU Multi-exposure image fusion (MEF) can produce an image with high dynamic range (HDR) effect by fusing multiple images with different exposures. The conventional MEF methods require significant pre/post-processing steps to improve the visual quality by reducing spatial artifacts. These methods may produce unwanted artifacts because of the limited processing power of mobile devices and complexities of
real scenes.

The Hong Kong Polytechnic University (PolyU)’s new MEF method decomposes an image patch into three conceptually independent components: signal strength, signal structure and mean intensity. By fusing these components separately, this approach can produce fused images with more vivid color appearances and fewer artifacts in both static and dynamic situations.
Special Features and AdvantagesAccuracy: Reconstruct HDR images with detailed structuresRobustness: Produce visually appealing results with very few artifactsFlexibility: Can be applied to both static and dynamic scenesApplicationsHDR imaging in consumer grade digital camerasHDR imaging in smart-phonesImage and video enhancementExplore further:Surgeons, CCTV and TV football gain from new video technology that banishes shadows and flare
