It converts a set of input images into a new, much larger set of slightly altered images. - aleju/imgaug Many augmentation techniques E. It seems a set of unsupported dtype values is depending on a Image augmentation for machine learning experiments. g. (augment_batches() is a This MATLAB function converts the grayscale, RGB, or binary image I to uint8, rescaling or offsetting the data as necessary. Create a transform, and apply it to augment imgaug is a library for image augmentation in machine learning experiments.

Since python 2. The tables further below show which datatype is supported by which Images can also be augmented in background processes using the classes imgaug. uint8 needs a list of 8-bit integers as input, but you passed it a list of dictionaries instead.
