OCRFeed gets frozen when you add multiple pages
Last modified: 2011-05-07 14:01:51 UTC
What steps will reproduce the problem? 1. scan 300 pages 2. open OCRFeed 3. Try to add all the pages to the OCRFeed's project What is the expected output? What do you see instead? i expected for a normal page recognition and i get a frozen program. What version of the product are you using? On what operating system? OCRFeeder 0.6.6 in Trisquel GNU/Linux Please provide any additional information below. when the OCRFeed get frozen it close itself i you cant work with it! :(
Hi Jorge, Can you tell how do you add those 300 pages (import from folder?) and if you have the Deskew images or Unpaper options configured to be used after an image is added (check the Preferences). What's the size of the images. Does it freeze when the images are being loaded or when you press recognize or another option?
Created attachment 186901 [details] a screenshot of my preferences in OCRFeeder

OCRFeeder get frozen one second later when i push the "Open" button for import all image from a folder :-|. this bug is present in the OCRFeeder 0.7.4 too :(.
Hmm, can reproduce the issue with about 20 images with the size you described... That image size and resolution is huge (even GIMP warned me about the size when I rescaled one of my scanned images) and I believe the program gets unresponsive and finally gets killed because of all the memory it is using. It could possibly be fixed on the application part by restraining the images to some size but this would likely influence the segmentation algorithm so I really gotta spend some time with it. On your side, maybe reducing the size/resolution could work for you and, depending on your images, still get good results.

Yeah, like I said, 300 images of such a big size is too much for the memory to hold, I'll take a better look into it when I can...
I think this a duplicate of #637599. *** This bug has been marked as a duplicate of bug 637599 ***
