transforms.RandomCrop(size, padding=None, pad_if_needed=False, fill=0, padding_mode='constant')#fill填充的像素大小,padding_mode:填充的模式(constant:填充fill设定的值, edge:填充边界的值, reflect or symmetric) 随机裁剪 transforms.RandomResizedCrop(size, scale=(0.01, 1.0), ratio=(0.75, 1.4), ...
Sigmoid函数将特征压缩到了(0,1)区间,0端对应抑制状态,而1对应激活状态,中间部分梯度较大。Sigmoid函数可以用来做二分类,但其计算量较大,并且容易出现梯度消失现象。
参数padding_mode表示边缘填充模式,边缘填充模式有:constant、edge、reflect、symmetric,默认值是constant,表示按常数填充。ToTensor表示转换成张量,Compose表示组合,参数transforms表示已transform为对象一系图像操作组成的序列。下面请看一个综合示例: Pad的运行结果如下所示: Normalize、ToTensor、Compose的运行结果如下所示: ...
