识别对象如下：trainset: 训练集合，该集合中从0~9的数字，所有图片大小相同。各个集合中的图像可以在Matlab中用imread函数读取为数组形式，用imshow函数显示出其图像，例如：图像0 (10).bmp可以用A=imread( 0 (10).bmp )读取为数组A，用imshow(A)或imshow( 0 (10).bmp )显示其图像。-Identify objects as follows: trainset: training set, the collection of numbers from 0 to 9, the same size as all the pictures. Each image in the collection can be read in Matlab using the imread function array form with the imshow function shows image, for example: the image 0 (10). Bmp can use A = imread (' 0 (10). Bmp ' ) read an array A, imshow (A) or imshow (' 0 (10). bmp ' ) display the image.
