kakul / alyn Goto Github PK

Hi,
I tried deskewing the image, but the program gave following error:
'
line 32, in deskew
rot_angle = 90 + angle + self.r_angle
TypeError: ufunc 'add' did not contain a loop with signature matching types dtype('S46') dtype('S46') dtype('S46')
'
Can you help me figure out the source??

I can`t get how you are calculating the angle of deviation, and why do we we calculate the average??

I used following commands to deskew input image
------python skew_detect.py -i 146_b.bmp
------./deskew.py -i 146_b.bmp -d Yes -o test.bmp -r 80

deskew.py line 1: Deskews file after getting angle: command not found

I install alyn module via pip, but pycharm shows that there are no deskew method and skewdetect method?

When I install Alyn on ubuntu16.04 via pip3,then I type a import alyn,I get the following message:

import alyn
Traceback (most recent call last):
File "", line 1, in
File "/usr/local/lib/python3.5/dist-packages/alyn-0.1.1-py3.5.egg/alyn/init.py", line 2, in

ImportError: No module named 'deskew'

can you help me figure out where is the problem?

Hi,

I have already pip installed alyn but it seems to still not be able to detect the alyn package. "import alyn" cannot work either. What should I do to fix this?

I have applied skew_detect and skew_correction on given image but its showing incorrect result. In image rectangle and text is not aligned properly.

Hi Folks,

does anybody know which is the original repository?

https://github.com/sbrunner/deskew
or
https://github.com/kakul/Alyn

Best regards

Hello,
I did some experiments and it looks like this method can't detect skews below one degree. Could you confirm this?

This is the output for the testing image (I manually introduced a skew of -0.5°):

Angle bins: [[0.50279329608938206, 0.50279329608938206], [90.0, 90.0, 90.0, 90.0, 90.0, 90.0, 90.0, 90.0, 90.0, 90.0, 88.994413407821213, 90.0, 90.0, 88.994413407821213], [], [-88.994413407821227, -88.994413407821227, -88.994413407821227, -88.994413407821227]]
Estimated Angle: 90.0
Average Deviation from pi/4: 44.6480446927

This is the ouput with a non skewed image:
Image File: c:\users\dturato\appdata\local\temp\1\tmp7u2snw.png
Angle bins: [[], [90.0, 90.0, 90.0, 90.0, 90.0], [], []]
Estimated Angle: 90.0
Average Deviation from pi/4: 45.0

So it looks like is detecting something, but it is someway lost in the final computation of the angle single value.

The current setup breaks with Python3. Work out a way to make this compatible with Python3.

My concern is skew_detect only and I installed this software via pip.

But there is no command installed. How can I use this?

I git-clone this repo and run skew_detect.py but it requires python-tk. Because I should run this server there is no GUI. Why does it depend on python-tk? The dependency is strange to me.

In sd.run() I am getting following error.

alyn-test/myenv/local/lib/python2.7/site-packages/skimage/io/_io.py:49: UserWarning: `as_grey` has been deprecated in favor of `as_gray`
