Image ghost removal
First Claim
Patent Images
1. A method for image ghost removal comprising:
- receiving an image and a first background model related to the image;
generating a foreground mask based only on the image and the first background model;
identifying image ghosts within the foreground mask; and
updating the first background model to eliminate the image ghosts without comparing the image to a second background model, wherein the identifying image ghosts entails a determination of an array of counts for each pixel in the image containing a number of seconds that the pixel has been continuously flagged as part of the ghost image in the foreground mask,and wherein the identifying image ghosts further entails measuring an amount of motion within the image ghosts to ensure that the image ghosts are not a foreground element.

Abstract
A method for image ghost removal is provided. The method for image ghost removal includes receiving an image and a background model related to the image, and generating a foreground mask based on the image and the background model. The method also includes identifying image ghosts within the foreground mask, and updating the background model to eliminate the image ghosts.

1. A method for image ghost removal comprising:
-
receiving an image and a first background model related to the image; generating a foreground mask based only on the image and the first background model; identifying image ghosts within the foreground mask; and updating the first background model to eliminate the image ghosts without comparing the image to a second background model, wherein the identifying image ghosts entails a determination of an array of counts for each pixel in the image containing a number of seconds that the pixel has been continuously flagged as part of the ghost image in the foreground mask, and wherein the identifying image ghosts further entails measuring an amount of motion within the image ghosts to ensure that the image ghosts are not a foreground element. - View Dependent Claims (2, 3, 4, 5, 6, 7)

8. A computer system configured for image ghost removal, the computer system comprising:
-
a memory configured to store images and background models; and a processor coupled to the memory configured to; receive an image and a first background model related to the image; generate a foreground mask based only on the image and the first background model; identify image ghosts within the foreground mask; and update the first background model to eliminate the image ghosts without comparing the image to a second background model, wherein the identifying image ghosts entails a determination of an array of counts for each pixel in the image containing a number of seconds that the pixel has been continuously flagged as part of the ghost image in the foreground mask, and wherein the identifying image ghosts further entails measuring an amount of motion within the image ghosts to ensure that the image ghosts are not a foreground element. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A non-transitory computer readable medium having stored thereon program instructions for image ghost removal, that when executed by a computer system, direct the computer system to:
-
receive an image and a first background model related to the image; generate a foreground mask based only on the image and the first background model;
identify image ghosts within the foreground mask; andupdate the first background model to eliminate the image ghosts without comparing the image to a second background model wherein the identifying image ghosts entails a determination of an array of counts for each pixel in the image containing a number of seconds that the pixel has been continuously flagged as part of the ghost image in the foreground mask, and wherein the identifying image ghosts further entails measuring an amount of motion within the image ghost to ensure that the image ghosts are not a foreground element. - View Dependent Claims (16, 17, 18, 19, 20, 21)
