The video pretty much explains it all: https://www.youtube.com/watch?v=CK0OCeCN9zg
I see in your video that you immediately dive into detecting possible characters and filter them by aspect ratio, size, etc.
I'm wondering why you wouldn't first look for rectangular-shaped objects, and feed those parts to the character recognition?
Could you explain your considerations? (Speed, reliability)

Hi guys.
I have a problem with OpenCV KNN.
After I run the software , its create the classification and image xml files, in softwrae location. But not show any things in the xml files,
Whats my problem?
I'm getting error
'ml': the symbol to the left of a '::' must be a type
'create': is not a member of 'CvKnearest'
what should I do?
when use multiple lined text inside the image the program pickup the single character randomly from any line and gives result in that sequence.
Thank you for writing and explaining the program ...
error: non-aggregate type 'std::vector' cannot be initialized with an initializer list
std::vector intValidChars = { '0', '1', '2', '3', '4', '5', '6', '7', '8', '9',
^ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
We are not able to recognise random images text,When we test using random images,it capturing whole image with Green boundary but not individual characters in the image.
Thankyou.
