图像比对是以原件的图像为基准，对待鉴定件图像进行预处理、定位、配准；再对原件及待鉴定件的图像进行相似度比对；计算出两者的相似度数值。 -Image than on the original image is based on identification of pieces of treated image pre-processing, positioning, registration again and to be identified on the original piece of

利用MATLAB的图像处理和数值计算功能得到颗粒物边界的二值图像；编制MATLAB程序，统计一系列以不同像素数量为边长的正方形块覆盖二值图像时的个数，根据像素数量和正方形块个数之间的关系，确定图像的计盒维数。-Image processing and numerical calculation using MATLAB function obtain pellets boundary of the binary image preparation of the MATLAB program,
