OCR Character Confidence
Posted: Fri Aug 07, 2009 7:55 am
I am doing OCR on an image and checking for Character Confidence.
for the Word FULL NAME when i use OCRTesseractGetCharConfidence
i get
F=19
U=19
L=19
L=19
N=65
A=65
M=65
E=65
When i debug in .Net i see the following values in the GDImaging Object
F=49
U=49
L=49
L=49
N=166
A=166
M=166
E=166
Can you tell me how these 2 values are related also which is more accurate the lower or higher value.
Also i have noticed that Confidence levels of a single word are always same as you can see above this is the case with other words as well. Is the confidence at Character or Word level.
