The task is to find braille located on a drugbox. I already managed to separate the braille from the rest of the image but now I'm stuck searching for a way to separate the 2 by 3 dots patterns, reading their meanings and returning the proper text in alphabetical characters. For my process so far see http://drop.io/dkh07pe . Thanks in advance for your help. > > > > do NOT double post(!)... > > CSSMers don't respond well to this kind of behavior... > > > > us > Sorry I don't understand... What do you mean by double post? I typed my question and then hit the "Post Mesage" button. I've never posted in a forum before so if I made some beginners mistake I hereby apologize. It looks in your case like an accident. Some times you hit the button twice or a faulty internet connection causes it to post twice. When to posts appear at the same time this is usually the case. Then again, there are others who post their question about PCA 7x. That's double (or septuple) posting! It's good practice to flag you second, accidental, post as 'duplicate post' or similar.

And what i'm currently searching for is a way to decode the braille by recognizing the patterns and giving back the corresponding alphabetical characters. Can i do this for example by creating matrices containing the patterns for each character and comparing these patterns to the pattern you see on the picture? And if yes how would the code look? |
