Contribute to ibbles/v2_normalize development by creating an account on GitHub. Normalizing the images means transforming the images into such values that the mean Normalization adjusts the range of pixel values in an image to a standard range, such as [0, 1] or [-1, 1]. Using the mean and std of Imagenet is a common practice. Normalize will use the mean and std to standardize the inputs, so that they would have a zero mean and unit variance. v2 模块中支持常见的计算机视觉转换。转换可用于训练或推理阶段的数据转换和增强。支持以下对象： 作为纯张量、 Image 或 PIL 图像的图 Bad normalization is one of the fastest ways to make a good model look broken. transforms.
