Highlights

In this release, we mainly focused on the technical debt as its decrease allows faster iterations and bug fixes in the codebase. We added only one new transform, did not work on speeding up transforms, and other changes are minor.

  1. We are removing the dependency on the imgaug library. The library was one of our inspirations when we created Albumentations, but maintainers of imgaug ceased its support which caused inconsistencies in library versions. It was done in 2021, say commit ba44eff by @Dipet .

But, somehow, we are cutting this dependency only in 2024.

  1. Added typing in all of the codebase. When we started the library, Python 2 was still widely used; hence, none of the original codebases had types specified for function arguments and return types. Since the end of the support for Python 2, we added types to the new or updated code, but only now have we covered all the codebase.

New transform

  • Added XYMasking transform: applies masking strips to an image, either horizontally (X axis) or vertically (Y axis), simulating occlusions. This transform is helpful for training models to recognize images with varied visibility conditions. It's particularly effective for spectrogram images, allowing spectral and frequency masking to improve model robustness.
    As other dropout transforms CoarseDropout, MaskDropout, GridDropout it supports images, masks and keypoints as targets. (004fabb by @ternaus )
