Motion-based image segmentor
First Claim
1. A method for segmenting an image, comprising:
- generating a joint histogram of a first image and a second image;
using said joint histogram to identify motionless information representative of a lack of motion between said first image and said second image; and
removing said motionless information from said second image.

Abstract
The present invention relates in general to systems and methods for using motion-based information to segment an image. In particular, the present invention relates to using a joint histogram to isolate a motion-based information of a moving person or object from an “ambient image” of the area surrounding and including the person or object in motion. An exemplary method or system for segmenting an image may include the steps of: generating a joint histogram of a first image and a second image; using the joint histogram to identify motionless information representative of a lack of motion between the first image and the second image; and removing the motionless information from the second image.

11. An image segmentation system for segmenting an image acquired with a sensor, comprising:
-
a histogram module providing for generating a joint histogram of a first image and a second image, wherein said joint histogram indicates motionless information representative of a lack of motion between said first image and said second image; and
a removal module providing for removing said motionless information indicated by said joint histogram from said second image. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21)

22. An image segmentation system for a vehicle safety restraint deployment application, comprising:
-
a sensor configured to acquire a plurality of images representative of an image source area, wherein said plurality of images includes a current image and a previous image;
a computer providing for;
generating a joint histogram of said current image and said previous image, wherein said joint histogram indicates motionless information representative of a lack of motion between said current image and said previous image;
removing said motionless information indicated by said joint histogram from said current image to produce a segmented image;
providing said segmented image to the safety restraint deployment system. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37)
