压缩图像作为 MAT 文件存储在磁盘上的目录compressedImagesDir中。计算出的残差图像作为 MAT 文件存储在磁盘目录residualImagesDir中。MAT 文件存储为double数据类型,以便在训练网络时获得更高的精度。 compressedImagesDir=fullfile(imagesDir,'iaprtc12','JPEGDeblockingData','compressedImages');residualImagesDir=fullfile...

Working with images in MATLAB is similar to working with any other type of matrix data, and you can display any two-dimensional data as an image in MATLAB. There are two common ways to display images:Read and Display Image File— Use imshow to display image files, which typically represent...
t10k-images-idx3-ubyte.gz: test set images (1648877 bytes) t10k-labels-idx1-ubyte.gz: test set labels (4542 bytes) 说明,4个文件分别表示训练图像集(预测变量)、训练标签集(响应变量)、测试图像集、测试标签集。 现在问题来了,这是什么鬼格式,如何查看图片,又如何使用数据集进行训练和测试?
