Error when trying to run Mex file #1

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Extract tesseract.zip
2. Add extracted folder to path, run tesseract.mexw32 (OS is Windows 7 32bit)
3. Get error: "??? Error using ==> tesseract Must call tessWrapper with the 
image to OCR."

How can I solve this?
Thanks in advance!

Hi, 

Maybe it is due to the way you call the function.

You may try this way:  text = tesseract(I); where 'I' denotes an 2D-uint8-array 
in matlab representing an image.

Using text=tesseract(I); is still giving the same error message.

Can anyone help?

Make sure "I" is an uint8 image. If you try to use an binary (boolean) image 
you will get the same error msg.

Thank you for your comment. Now tesseract command is running. Unfortunally, the 
result doesn´t make sense (not normal caracteres, special ones as result). I 
have tried a on-line page that use tesseract and the result was perfect. Do you 
have some idea?

I too have the problem. The tesseract(I) function is giving me very inaccurate 
and weird characters. My input image is a grayscale uint8 2-d array image. 
Other tesseract implementations seem to work fine. Do i need to train the 
system? Does anyone have any more information on this issue?

Thanks.

 i am also facing the same problem as  reje...@gmail.com .   
the result doesn´t make sense (not normal characters, special ones as result)
i am using the command text=tesseract(I); and I is  unit8 image.
I am giving it a b&w image after some processing, so my image contains only 
text and few white patches here and there.
plz help
i am attaching the input file and extracted text.

As mentioned in previous mail, iam giving a binary image with only one alphabet 
'B' as input. 
The results of using 'text = tesseract(I)' is 'U3 U3 U3' which is not 
equiavlent to alphabet 'B'.
Can any one of you people suggest us how to use this Tesseract wrapper.. Any 
suggestions would be really great.

Change the image class, from double to uint8.

WRT your previous mail, my image class is of uint8 and not double. Still for 
the alphabet 'B', it is giving weird results 'U3 U3 U3'.Any suggestions would 
be really great.
