Nodules augmentation #294
This issue dedicated to one possible improvement in the current pipeline of
The augmentation described in their pipeline is trivial affine transformations which have been described and implemented in PR #132. Though it's good enough to achieve eminent results, I think there is an area of investigation and the potential gap to be filled. My proposal is to classify nodules by their type of appearance and proximity to other structures: Juxta Plural, on the coastal line of lungs, Juxta Vascular, which appears on the blood vessels and typically grow most rapidly 1, and Isolated which placed in the lung. These three types are depicted below, accordingly.
Then, since we can well segment nodules, crop them out and based on vessels & lungs segmentation (described in #138) find appropriate spots to place them in the aim to artificially enlarge dataset and therefore improve generalisation capability of the
Any thoughts will be highly appreciated!
