最近又研究了一下MRC压缩，搞了一个新版本，使用paddle的版面识别功能，文字全部蓝黑二值化，图片和表格保留彩色。（私货：蓝色用的是和头像一样的色号🤣） ![屏幕截图 2026-06-22 220303](https://forumcdn.freemdict.com/uploads/default/original/3X/3/f/3fe6e6729b965e556596bfbfede659ef0766d927.png) 上面的链接已经更新。 ---

Thank you, but I need the original scan quality, 600dpi I assume, but the book uploaded in zlibrary I think It has 300dpi resolution which is not enough for precision OCR task, because of small text or tiny character in pronunciation. ---

Well, the original PDF is also 300ppi. But of course, JPG is more suitable for OCR than binary images. ---
