General Notes

• The program only works for TIFF files. It rejects PDF, JPEG, and other files. It is a good idea to build your TIFF files with compression (LZW works well). The program can handle multiple-page TIFF files.
• The program does not handle English letters. If you have an image of a bilingual text, it will try to understand each letter as a Yiddish letter.
• Any letter that the program does not recognize will result in the "▯" character.
• I have trained the program on printed texts. It doesn't recognize computer fonts very well.
• It is best to submit a very clear, high-resolution image in simple black/white. The background must be white, the letters black. The lines must be very close to horizontal. Images from the National Yiddish Book Center are often good.
• The program is set to ignore characters that are too small (fewer than 10 pixels wide and high).
• Please send comments to raphael at cs dot uky dot edu. I look occasionally at the images that you download, and I use your high-quality images to improve the recognition rate of my program and to discover bugs that I need to fix.
• The program works best if I set certain parameters to match the characteristics of your TIFF file. This web version just uses standard settings. If you really need a particular document analyzed well, it takes about an hour to train the program to its peculiarities. Contact me.
