A method and device for estimating a color mapping between two different color-graded versions of a sequence of pictures |
摘要 |
The present disclosure relates to a method and device for processing a sequence of pictures comprising estimating a color mapping between a first color-graded version of said sequence of pictures whose values are represented in a first color volume and a second color-graded version of said sequence of pictures whose values are represented in a second color volume. The method is characterized in that it comprises:
- obtaining (10) a first composite picture by assembling at least two pictures temporarily located at determined time instants in the first color-graded version of the sequence of pictures, and a second composite picture by assembling a same number of pictures temporarily located in the second color-graded version of the sequence of pictures at the same determined time instants; and
- estimating (20) said color mapping between said first and second color-graded versions of the picture by estimating a color mapping function that maps the color values of said first composite picture onto the color values of said second composite picture. |
