| How to run UNLV tests. |
| |
| The scripts in this directory make it possible to duplicate the tests |
| published in the Fourth Annual Test of OCR Accuracy. |
| See http://www.isri.unlv.edu/downloads/AT-1995.pdf |
| but first you have to get the tools and data from UNLV: |
| |
| Step 1: to download the images goto |
| http://www.isri.unlv.edu/ISRI/OCRtk |
| and get 3b.tgz, Bb.tgz, Mb.tgz and Nb.tgz. |
| |
| Step 2: extract the files. It doesn't really matter where |
| in your filesystem you put them, but they must go under a common |
| root so you have directories 3, B, M and N in, for example, |
| /users/me/ISRI-OCRtk. |
| |
| Step 3: Reorg the files |
| The lack of tif extensions on the images is inconvenient, so there |
| is a script to reorganize the data to match the rest of the test |
| scripts. |
| cd to /users/me/ISRI-OCRtk or wherever 3, B, M and N ended up and run |
| /blah/blah/tesseract-ocr/testing/reorgdata.sh 3B |
| This makes directories doe3.3B, bus.3B, mag.3B and news.3B. |
| You can now get rid of 3, B, M, and N unless you want to get some of the |
| other scanning resolutions out of them. |
| |
| Step 4: Download the ISRI toolkit from: |
| http://www.isri.unlv.edu/downloads/ftk-1.0.tgz |
| |
| Step 5: If they work for you, use the binaries directly from the bin |
| directory and put them in tesseract-ocr/testing/unlv |
| otherwise build the tools for yourself and put them there. |
| |
| Step 6: cd back to your main tesseract-ocr dir and Build tesseract. |
| |
| Step 7: run testing/runalltests.sh with the root data dir and testname: |
| testing/runalltests.sh /users/me/ISRI-OCRtk tess2.0 |
| and go to the gym, have lunch etc. |
| |
| Step 8: There should be a file |
| testing/reports/tess2.0.summary that contains the final summarized accuracy |
| report and comparison with the 1995 results. |
