英文摘要：

A method of detecting moving objects is proposed by combining the Gaussian mixture model with the canny operator. First, the Gaussian mixture model was employed to extract color information and to update the background information. Second, the canny operator was employed to extract edge information. Last, color information and part of area information were integrated for segmentation, which improved the ability to detect moving objects where edge information was distinct. An improved Gaussian mixture model and a traditional canny algorithm were employed in the experiment. Experimental results indicate that the proposed method is superior to the traditional Gaussian mixture model.
