常見例句雙語例句Mixture Gaussian model is one of background subtraction methods.混合高斯模型是背景對消中一種非常有效的方法。First, we consider the dependency of parent-child wavelet coefficients by the use of mixture gaussian model and we get the fitting result by the method of EM(Expected Maximum).通過小波父子系數(shù)的聯(lián)合分布密度函數(shù)來描述小波域中各相鄰尺度系數(shù)的非獨立特性,運用期望極大估計(EM)算法實現(xiàn)對該聯(lián)合分布密度的混合高斯模型擬合;Background modeling was based on mixture Gaussian model, which had strong adaptive capability for variety of external factors, such as illumination change, shadow, object shelter and etc.采用混合高斯模型為碼頭背景建模,該模型可克服各種外部因素的影響,如光照變化、陰影、目標(biāo)遮擋等,具有很強的適應(yīng)能力。 返回 mixture gaussian model
