The set of detail images are enhanced after which noise reduction filtering is directly applied to the enhanced set of detail images without the need to apply noise estimation to a local area of the enhanced set of detail image in advance. The residual image and the set of detail images with reduced noise are recomposed so as to obtain resultant image."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for multi-scale based dynamic range compression and noise suppression","description":"An input image is decomposed into a residual image and a set of detail images in different levels of a hierarchy.
