Abstract
Official abstract text for this publication.
A human tracking method using a color histogram is disclosed. The human tracking method using the color histogram according to the present invention can more adaptively perform human tracking using different target color histograms according to the human poses, instead of applying only one target color histogram to the tracking process of one person, such that the accuracy of human tracking can be increased. The human tracking method includes performing color space conversion of input video data; calculating a state equation of a particle based on the color-space conversion data; calculating the state equation, and calculating human pose-adaptive observation likelihood; resampling the particle using the observation likelihood, and estimating a state value of the human; and updating a target color histogram.
First claim
Opening claim text (preview).
What is claimed is: 1. A human tracking method using a color histogram comprising: creating color-space conversion data by performing color space conversion of input video data; calculating a state equation for each of a plurality of particles based on the color-space conversion data, the state equation including a state variable representing a human pose that comprises a position of a human and a rotation angle of the human; calculating, for each particle, a human pose-adapti…
