Description

Intensity augmentation transform to be used as a means of data augmentation for medical imaging datasets. It was first demonstrated in Intensity Augmentation to Improve Generalizability of Breast Segmentation Across Different MRI Scan Protocols that intensity augmentation helps generalize a model. It has been used in other works such as Image translation for medical image generation: Ischemic stroke lesion segmentation.

The transform works by replacing the intensities of an image by new values uniformly sampled from all possible intensity values in the input image. Below is an example of the application of the transform on an MRI image:
