Abstract:
1. A method implemented in an image processing system for combining multi-exposure images, comprising: obtaining a plurality of images having different exposure levels for a same scene; constructing a merged weight map for at least one obtained image by determining at least one merged weight value for at least one pixel of each obtained image based on characteristics of the at least one pixel, wherein the merged weight map comprises a weight map corresponding to the plurality of images; generating a Gaussian pyramid and a Laplacian pyramid of each obtained image; generating a Gaussian pyramid of the merged weight map; generating a merged Gaussian pyramid and a merged Laplacian pyramid based on the Gaussian pyramid of the merged weight map; generating an intermediate pyramid based on the merged Laplacian pyramid; and constructing a resultant image by blending the merged Gaussian pyramid with the intermediate pyramid.
