1、读入图片，根据PGN格式的line 2 确定矩阵的大小为 28*28=784，根据line4 获取.
2、读入图片，根据PGN格式的line 2 确定矩阵的大小为 28*28=784，根据line4 获取。
3、计算平均矩阵。
4、对平均值矩阵进行SVD：
5、平均矩阵进行SVD后的前20个singular vector的输出结果。
6. 将训练集的每一张图片当成一行，形成一个矩阵，然后对矩阵进行PCA分解。
7. 这个矩阵对测试集的每张图片进行降 维，得到的图像。(1, read the picture, according to the line 2 of PGN format, the size of the matrix is 28*28=784, obtained according to the line4.
2, read the picture, according to the line 2 of PGN format, the size of the matrix is 28*28=784, obtained according to the line4.
3. Calculate the average matrix.
4. The average value matrix is SVD:
5. The average matrix carries out the output of the first 20 singular vector after SVD.
6. take each picture of the training set as a line, form a matrix, and then decompose the matrix by PCA.
7. this matrix reduces the dimension of each picture of the test set and gets the image.)
