Data augmentation: ImageDataGenerator vs openCV

WebSep 16, 2024 · 1. Keras' ImageDataGenerator doesn't offer much support by itself for data augmentation. However it has a parameter called preprocessing_function which allows you to use custom augmentors with it. I personally use imgaug which offers virtually any augmentation you can think of and works well with ImageDataGenerator like I said. WebNote. In 0.15, we released a new set of transforms available in the torchvision.transforms.v2 namespace, which add support for transforming not just images but also bounding boxes, masks, or videos. These transforms are fully backward compatible with the current ones, and you’ll see them documented below with a v2. … pourvoirie itouk mont valin
