The low size of the pages did not help to process. I would have expected 1 meg per page. I have just finished a newspaper under A3 in size and was 130-150 meg per page. Because of the size of the files it is difficult to say if the quality is good enough to produce a epub file. I have seen worse but not for a book.
Attached are files before and after editing. It was difficult to see , and . epub is not an extension that can be uploaded so I have included a Word file.

When scanning try to scan with pages on the same plane as the desk. If you have a thick book the distance between page and camera changes quite a bit, which effect font size and page size. For epub this is not a issue.

It would have been good to see a scan before page spliting.

I am using a Avision book scanner and some times scan 2 pages at a time. In ABBYY Finereader one can do auto or manual splitting pages, I usually do manual. If the pages are reasonable flat you could leave them joined, lines in both pages need to straight across though.

This happened to me three times not sure what caused it. I had to keep picking the book up to maneuver it otherwise it would only scan half a page. The line to split the pages was never were the scan showed so I had to keep moving the book back and forth until I had a decent page scanned. It took me a lot longer than 5 seconds to take a scan like the manual said. More like 2 minutes and at this point I'm so frustrated with this scanner I'm thinking of sending it back.
If you are able to return the iOCHOW easily that would probably be a good move: while it may be possible to obtain better results than you have so far, you would probably be better off using one of the much better known CZUR scanners...

Regarding the images you attached: when viewed the page size is shown as about 3" x 4.5", which I imagine is at least somewhat smaller than the book pages? Consequently, with the indicated image DPI of 96 the text quality is quite poor, maybe a scanner settings issue. Edit: Or have you actually posted screenshots?

And are the book pages actually that yellowed, as your finger looks a normal colour, maybe they are?

So I took these photos with my Google Pixel phone. And I see what you meant by the quality of the picture. I was blown away. Does ABBYY have a feature to fix the photo to flatten the curve? I could just use my phone and save myself a lot of trouble.

These photos are half the size of the last lot. But still work. Abbyy does not have the flatten curve feature but it does have 'Straighten text lines' feature. This is the first time I have used the feature. You should be able to see this in the pdf file. The doc file is really a epub file so you will need to rename it.
No editing has been done except the 'Straighten text lines' feature.

Instead of finger on corner try fingers top and bottom at the centre of the page to reduce curve. You will then need a creative way to take the photo. I have seen a glass sheet and frame design that flattens the page for you. Its on this site.

You can get away with a lot if you only want text.

You might also look at some of the recent smartphone scanning apps, some of them look impressive and might provide very useful preprocessing including curve flattening at minimal cost, either prior to using FineReader, or possibly in place of it if they support OCR.

Edit:

One of many in a search 'smartphone scanning app', vFlat specifically refers to curvature and finger removal; there are also Abbyy camera scanning apps.
