Abstract
Provided are a system and method for determining a color of a foreground and a computer readable recording medium therefor. The system includes: at least one processor configured to implement a motion detector which detects a motion region from an image; and a color determiner which determines the color of the foreground in the motion region based on a difference between colors of the motion region and colors of a surrounding region of the motion region, for displaying the determined foreground color with the foreground at a display device.
Claims16
A system for determining at least one color of a foreground, the system comprising:
- at least one processor configured to implement:
- a motion detector configured to detect a motion region from an image;
- and
- a color determiner configured to
- i) determine the color of the foreground included in the motion region based on a difference between at least one color of the motion region and at least one color of a surrounding region of the motion region
- ii) generate a color histogram of the surrounding region and a color histogram of the motion region,
- iii) obtain a color histogram of the foreground based on a difference between the color histogram of the motion region and the color histogram of the surrounding region, and
- iv) determine the color of the foreground from the color histogram of the foreground, for displaying the determined color with the foreground at a display device,
- wherein the color of the foreground is a representative color which has the highest frequency in two or more colors of the foreground shown in the color histogram of the foreground.
A method of determining at least one color of a foreground, the method comprising:
- detecting a motion region from an image;
- and
- determining the color of the foreground included in the motion region based on a difference between at least one color of the motion region and at least one color of a surrounding region of the motion region, for displaying the determined color with the foreground at a display device,
- wherein the determining the color of the foreground comprises:
- generating a color histogram of the surrounding region and a color histogram of the motion region;
- obtaining a color histogram of the foreground based on a difference between the color histogram of the motion region and the color histogram of the surrounding region;
- and
- determining the color of the foreground from the color histogram of the foreground,
- wherein the color of the foreground is a representative color which has the highest frequency in two or more colors of the foreground shown in the color histogram of the foreground.
