【摘要】:針對傳統(tǒng)粒子濾波跟蹤算法中的目標(biāo)模型單一、粒子退化等問題,文章提出了一種基于顏色特征與紋理特征自適應(yīng)融合的粒子濾波跟蹤算法,該方法選取顏色特征和紋理特征作為目標(biāo)的視覺描述子,然后將2種特征的后驗概率進(jìn)行融合,并對目標(biāo)模板進(jìn)行自適應(yīng)更新,進(jìn)而估計出目標(biāo)的狀態(tài)。實驗結(jié)果表明,該方法能夠較好地處理背景光照變化明顯、目標(biāo)物體與背景顏色相近、遮擋、局部形變等干擾因素的影響,準(zhǔn)確跟蹤及定位運動目標(biāo)。
[Abstract]:Aiming at the problems of single target model and particle degradation in the traditional particle filter tracking algorithm, a particle filter tracking algorithm based on adaptive fusion of color features and texture features is proposed in this paper. The color feature and texture feature are selected as the visual descriptors of the target, then the posterior probability of the two features is fused, and the target template is updated adaptively to estimate the state of the target. The experimental results show that this method can deal with the influence of disturbance factors such as background color, occlusion, local deformation and so on, and accurately track and locate moving objects.
