Hello, Some older fax machines used different DPI in horizontal and vertical directions. This often resulted in images with jagged lines as in the file that I have attached to this post.
I am trying to find a way to smooth these out to improve OCR accuracy. The images are already in 1-bit monochrome and compressed using CCITT G3 (FAX) format. My objectives are to smooth the lines and edges, as well as, remove the grid lines if possible. These are archived images and the source paper documents are no longer available. Any guidance on appropriate image processing algorithms (preferably using Leptonica) will be greatly appreciated.
