AS you have a connectivity issue while uploading - catch it and discard the image! Way simpler than processing image later...

Agree with ^.

And you'd have to define partially anyway. A full page of printed document is partially filled because it has margins so you're going to have a very hard time defining partial.

If these are files then maybe you can look at file size to try and queue some up that need to be looked at by somebody.

A simple way might be to use an OCR library, if this does not return any text the page is probably blank or contains only images: https://www.slant.co/topics/2579/~best-ocr-libraries[^]

Another way might be to use contour analysis, if the contours are not over the entire page then you have found a (partial) blank page.
Here is a CodeProject article with some examples: Contour Analysis for Image Recognition in C#[^]
