    经常看到

    transform.ToTensor(),
    transform.Normalize((0.5,0.5,0.5),(0.5,0.5,0.5))

    那transform.Normalize()是怎么工作的呢?以上面代码为例,ToTensor()能够把灰度范围从0-255变换到0-1之间,而后面的transform.Normalize()则把0-1变换到(-1,1).具体地说,对每个通道而言,Normalize执行以下操作:

    image=(image-mean)/std

    其中mean和std分别通过(0.5,0.5,0.5)和(0.5,0.5,0.5)进行指定。原来的0-1最小值0则变成(0-0.5)/0.5=-1,而最大值1则变成(1-0.5)/0.5=1.
