Actually, my goal is to make a proof of concept (PoC) to see 1) if this function is useful and 2) under what constraints. I finally found what was my problem. A .cxx was not automatically recompiled after modification of a header. make clean and make do the trick. I will try to create a branch on gerrit once all will work. It should take a week. I decided to use NN because I know how to use it to do recognize of character. The PoC and feedback will tell if it's a good idea. I decided to use 15*15px to reduce size of the NN. Actually, the NN generated by fann is a 300Mo plain text file. Increasing the size must be testing. And improving the size of internal layers of the NN is a need but it's out of my skill. Actually, the number of characters is about 2200. But I found there's a way to use all of them. It will increase by a lot the number of characters. Theoretically, a NN can handle any number of character. The NN need X input (number of pixels of the image to recognize) and Y output (number different character). But this will increase, again..., a lot the cache. I will continue to work on it now I'm not stuck anymore and will keep you in touch when the PoC will be finished.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
