在深度学习领域，图像增广是提升模型泛化能力的关键技术之一。PyTorch库提供了丰富的图像增广API，其中最常用的包括ColorJitter和CenterCrop。ColorJitter函数允许我们对图像进行颜色调整，具体包括亮度、对比度、饱和度和色调的修改。例如，brightness参数用于控制图像整体的亮度变化，contrast参数则用于调整图像的对比度...

Relevance means that different augmentations of the same image (such as mask, shuffle) are related in the feature space. For example, the distribution of the image after the mask should be close to that of the original image. Rationality means that the molecular structure must conform to ...
