Removing noise in doctr

[navaneeth-nagu]

Hi team,

Does doctr remove noise in the document or if there is a better way to remove the noise? Please suggest.

Thanks in advance.

Hi @navaneeth-nagu 👋,

The only things we do by default are resizing the inputs and normalizing so no we don't remove noise :)

multi_img_doc = DocumentFile.from_images(["path/to/page1.jpg", "path/to/page2.jpg"])

The DocumentFile returns a list of numpy arrays so you could do with it whatever you want (for example any OpenCV operation) before passing the list of np arrays to the model/pipeline

Or you use a AutoEncoder to remove noise i have worked on something a few years ago (maybe useful as reference):
