How I did it:
0. Download and install Tesseract

1. Crop and adjust curves of the image in Paint.Net (= get a better contrast) to ease OCR
2. Save as PNG in the folder of Tesseract
3. Open cmd in Tesseract folder, type tesseract kayak.png kayak (produces kayak.txt)
4. Open kayak.txt in Notepad++, remove empty lines (to have correct indexes), CTRL+F "KAYAK"
- brusch64 12y agoHow do you do OCR in Paint.Net ?
- column 12y agoIn Paint.Net I only adjusted the curves (CTRL+SHIFT+M) to get a better contrast. The OCR is done by Tesseract. This solution is all about using the right tool for the job.
- brusch64 12y agoSorry I misunderstood your comment. Was just wondering how you are doing OCR in Paint.Net. Thank you for your clarification.
- column 12y agoThis is the output of Tesseract (once empty lines are removed): AAYKAKAYKAYYKKAAKAYAAAYKYKYAYK KYYAKYAAAYKAAKKYAKKKAAAKAAYKAA KKKYAKAKAYKKYKKYKKAKYAAAAKAAKK YKAAKYAAKKKKKAYAYYYYYAAKAAKKKK KKAYYAAKKYYAYAAKAAKKAAYKAKKAAK KKAAAKAAAKKAKKKYAAAYKYAYAKYKAA KKYKAAAAAAAAAAKKAAAKYYAKAKAKKY KKKKKKAKYYKYYKKAAYAKAAAKYAKKAA KAKKAKAYKAAYAKYYKKAYKKKAAAAAKA KKAKAKAKAAAKAYAYKAKAYYAYKKAKYY AAAYAKKKAKKAKYKAYKKAKKYKAAKKYY YKKKYKKYAAAKKKKAKAYKKKKKAAKKKY KKAKAYKAAKAKKYYAKAYAAKYAAAAAAA AAAAKKYAAKKAAYKKAAAYAYAKYAKAYK AKKAKKAYKAAYKYKAKYAAKKYKKKKKKA KYKAAKKYAYKAKKKYKAKAYAYKYAAAKK KAYYKKAKYKAYAAKAYAAYYYAKKYKYKK KKKKAKAYAAAKKAYAYKKYAKAAAAYKAY AYKAKKKAAKAKAYAAAKKYKKAYKAYAYY KYAYKAYAKAKYYKYKAKAAYKYKKAYKAK AKAKKAKKAKKKKAAAKYYYYKAKAAAAAK KAKYYKAKKYKYAKYAAAAAKAKAYAAKKA KKAAAKKAKAKKAAKAYAAYAAAKKAAYYA KAKKYYKKAYAYKKAKKYYKYKYKKAAAKA
- jjnoakes 12y agoDoesn't this only work if the word is west-to-east? Seems like it'd fail for any other orientation (there are 7 others). (Well, for a palindrome, it works for east-to-west too - so I guess you missed 6).
- column 12y agoYou are correct. However, it is stated that 'KAYAK' appears only once and it seems to me that CTRL+Fing should be the first thing to do when searching for a string in a relatively small text. The next step, had the CTRL+F failed, would have been to search for "KAYAK" vertically/diagonally programmatically. (on a sidenote, you're counting is incorrect, as it is a palindrome there really is only 4 directions for the word to appear: W-E, N-S, NW-SE, NE-SW)
- pacofvf 12y agofor vertical, you could transpose the crossword then Ctrl+F, just being aware that the result has its columns and rows switched.
