InvertOrNot

Make your app's dark-mode smarter with InvertOrNot. Our API predicts if an image should be inverted for optimal dark-mode rendering. This API is free, and is open source (both the code and the weights of the model are available).

Background

Despite dark-mode's popularity, images often aren't automatically adapted to fit it. The conservative approach is to reduce the brightness of the image, which can degrade it significantly. Inverting the image can be a better solution, but it can't be applied to all images (see the poor Queen Victoria). Using our API you can make your website more pleasant to use in dark-mode, without having to manually adapt each image.

How does it work?

The API works by finetuning an EfficientNet model on a custom dataset using PyTorch. By using deep learning we are able to have a much more reliable approach to solve this problem, the only alternative being heuristics.
