Abstract
Guided filtering is applied, with a camera raw image as a guidance image, to a first image to generate an intermediate image. A dynamic range mapping is performed on the intermediate image to generate a second image of a different dynamic range. The second image is used to generate specific local reshaping function index values for selecting specific local reshaping functions. The specific local reshaping functions are applied to the second image to generate a locally reshaped image.
