Method for Discriminating Textures Regions and Homogeneous or Flat Regions in an Image and Methods for Estimating Noise in an Image Sequence

摘要

A method for discriminating textured regions and homogeneous or flat regions in an image. A multi-scale or multi-resolution measurement is performed with respect to the image. Alternatively or additionally, the image is analyzed by using a prior measured noise value and a local variance value in or with respect to the image.
