Hi chris. I heard cnn is more accurate than knn. Is that possible to use cnn in emgu?

[kleberbueno.]

Cris thanks in advance for this.
I am trying to code it in java. And I got a issue. The serialization used in VB generates .XML file with set os characters alpha numeric. The serialization in Java only generates number. Do you have any idea on how VB generates alpha chars if only numbers are in the array?

hi sir, when i first run the program after renaming Form1 to frmMain, i cant find the BC30456 error, is that a problem?

[izzatulaisyahmohdsalleh]

thank you very much for the tutorial~ it has helped me greatly in my studies however i have been trying to use your program to detect black number plates with white letters and it has been failing so far and well im not sure why
i have tried changing the training files to black and white and it seems that the accuracy has increased by a smidgen but it still fails miserably only managing to detect at most 2 /6 letters at all times.
i have a suspicion it might be due to a number of factors such as the font of the letter as well as the spacing between letters but im not too sure on how to integrate it into the algorithm that you have shown above.
i hope to hear from you soon.
thank you for your help.

Is it possible to use this for a background window? Like OCR running and analyzing texts for another program.

Anyone having issues with the latest emgu change this line "imgTrainingNumbers = CvInvoke.Imread(ofdOpenFile.FileName, LoadImageType.Color)" for this line "imgTrainingNumbers = CvInvoke.Imread(ofdOpenFile.FileName, ImreadModes.Color)" to get it working. This resolves error BC30451 'LoadImageType' is not declared. It may be inaccessible due to its protection level.
