imgaug
imgaug is a powerful Python library designed for image augmentation, which is a critical component in the field of 機械学習, particularly in コンピュータビジョン tasks. Image augmentation refers to the process of artificially expanding a dataset by applying various transformations to the existing images. This helps to improve the robustness and performance of machine learning models by providing them with a more diverse set of training examples.
