|
|
Hi all, I have a question for any of you who knows the topic "image recognition".
I was recently asked, as a sort of "favor", to develop a small software, which task is to recognize a certain number of pre-determined (small) details in a target image (such as patterns inside a complex image).
The guy who asked me such a thing is completely ignorant of programming, however, even if I'm a programmer, I never meddled with image recognition and I don't know if I'm up to the task.
Can anyone please tell me if there exists some already well-developed piece of software (like an opensource library) that already do the work? Is there some piece of software that can be "easily" modified? Is there some place where I could read some pertinent information (without reading ALL the literature on image recognition) in order to write something from scratch? I appreciate any kind of information that you can share with me.
Thanks in advance. _________________ Any mans death diminishes me, because I am involved in Mankinde; and therefore never send to know for whom the bell tolls; It tolls for thee.

I'm no programmer and never used OCR (Optical Character Recognition).
But here a scanned page is analysed for patterns too.
The scanner outputs a jpeg or tiff or other graphical type of picture.
Then the OCR software converts it to a text file that can be loaded into an editor.
There's quite a few opensource programs around.
Hope this will be a start for you.

Take a look at media-libs/opencv and related projects. It is widely used for face/feature recognition. _________________ "The only difference between me and a madman is that I am not MAD" (SALVATOR DALI) |

Ok openCV seems a good staring point. Thanks. _________________ Any mans death diminishes me, because I am involved in Mankinde; and therefore never send to know for whom the bell tolls; It tolls for thee.
