Abstract
A method for tracking an object in a video data, comprises the steps of determining a plurality of particles for estimating a location of the object in the video data, determining a weight for each of the plurality of the particles, wherein the weights of two or more particles are determined substantially in parallel, and estimating the location of the object in the video data based upon the determined particle weights.
Claims15
A method of tracking an object in a video data, comprising:
- determining a plurality of particles for use in estimating a location of the object in the video data;
- determining a weight for each of the plurality of the particles, wherein the weight of two or more particles is determined substantially in parallel;
- and
- estimating the location of the object in the video data based upon the determined particle weights.
The method of any preceding claim, wherein the weight of each particle is based on a plurality of information cues.
A computer program product comprising a computer-useable medium having a compute readable program code adapted to be executed to implement a method for tracking an object in video data as claimed in any preceding claim.
An apparatus for tracking an object in a video data, comprising:
- a first processing unit arranged to determine a plurality of particles and to estimate the location of the object in the video data based upon a weight of each of the plurality of particles;
- and
- a graphics processing unit arranged to determine a weight for at least some of the plurality of the particles, wherein the weight of two or more particles is determined substantially in parallel.
