Unable to detect orientation #1345

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Rotate image
2. Process the image with pagesegmode set to auto osd
3. Detect orientation

What is the expected output? What do you see instead?
I expect the orientation to tell me what the orientation of the image is. 
Instead the orientation is always page up. 

What version of the product are you using? On what operating system?
3.02 on windows 7

Please provide any additional information below.
I have taught tesseract a new font which helps pick up this image with 91% mean 
confidence. However when I rotate the image I'm unable to detect the 
orientation. I have attached the image file.

Can you provide more detail what you did?
I tried this (with recent repository code):
    tesseract Original.JPG - -psm 0
and I got:
    Too few characters. Skipping this page
e.g. there is not enough characters for orientation and script detection...
