Abstract: AIM　Automatic measuring and quantitative analysis of form feature parameter of the liposome and emulsion image. METHODS　On the basis of analyzing the form feature of liposome, some algorithms, such as the logical algorithms of mathematical morphologic, the grayscale-gradient co-occurrence matrix-based method and the image enhancement method of grayscale image, were used to construct the parameter of extracting method and software. RESULTS　The noise is restrained effectively and the definition of image increases, implementing the automatic measuring of particle parameters. CONCLUSION　The analytical result of bipolysaccharide liposome and some emulsions indicate that the method can definitely increase the speed and precision of the measurement.
