Methods and systems for combining foreground video and background video using chromatic matching
First Claim
1. A method comprising:
- obtaining foreground video data;
obtaining background video data;
determining a color-distribution dimensionality of the background video data to be either high-dimensional chromatic or low-dimensional chromatic;
selecting a chromatic-adjustment technique from a set of chromatic-adjustment techniques based on the determined color-distribution dimensionality of the background video data;
adjusting the foreground video data using the selected chromatic-adjustment technique;
generating combined video data at least in part by combining the background video data with the adjusted foreground video data; and
outputting the combined video data for display.

Abstract
Disclosed herein are methods and systems for combining foreground video and background video using chromatic matching. In an embodiment, a system obtains foreground video data. The system obtains background video data. The system determines a color-distribution dimensionality of the background video data to be either high-dimensional chromatic or low-dimensional chromatic. The system selects a chromatic-adjustment technique from a set of chromatic-adjustment techniques based on the determined color-distribution dimensionality of the background video data. The system adjusts the foreground video data using the selected chromatic-adjustment technique. The system generates combined video data at least in part by combining the background video data with the adjusted foreground video data. The system outputs the combined video for display.
