[rohitvarghese]

Thank you so much...Finally Installed!

[rohanghige]

Really nice video..clear explanation...
Can you put some tutorials regarding basic image processing in open cv?

[naqiazam]

thank you so much for sharing your knowledge that was very helpful

Is there a way to install OpenCV for Python 3.4 on Ubuntu 14.04? It seems not to be straight forward and I couldn't find any tutorials.
Thank you and great vid!

[billyzhong]

it's very useful, thanks for sharing dude!

The initial list of commands in your video doesn't quite match your comment list? Also I am using OpenCV 3.1.0 though I assume most of these commands will be easily adapted?
Do you possible have an newer installation tutorial?

[cesco]

Thanks, for the Comment. Yes, I will be doing some of those.

I keep getting this error despite of following all the steps, I even set the PYTHONPATH to source directory but it still gives the error, how do i solve this?
Traceback (most recent call last):
File "turing.py", line 20, in <module>
import cv2

[dimuthrs]

Wow, a great help to me. Thanks a lot. Really nice video. It works!! :-)

Hi, after I finish: make, and sudo make install, there are no errors. However, after this step, when I run the following step: sudo gedit /etc/ld.so.conf/opencv.conf, it has error. I didn't find the file opencv.conf in this directory, is any thing wrong?? thanks

[anupamyedida]

i am not able to save the gedit file of bash.rc . It is telling me that i do not have permission.
Could you please tell me how I could solve this ?

[tomava]

Actually, I have to use gedit to creat such a file. I have figured it out.

[sumoking]

i have problem on this code : sudo apt-get build-dep libopencv-dev,
when i enter, the system keeping E:You must put some 'source' URIs in your sources.list.
Why???hope can get answer from u..i m strugling for half day on finding solutio, , ,

[cedriccarteron]

Hi, I am all new in Ubuntu and I tried doing this:
"sudo apt-get install python-numpy python-scipy python-matplotlib ipython ipython- notebook python-pandas python-sympy python-nose".

However, my computer is unable to locate package of both notebook and python-pandas. As you said, I simply copied and pasted it.
Could anyone tell me what went wrong ?

Hey..I just wanted to ask if this Opencv Programming can process the image of 
Bacteria..?thank you..

Hello sumo,
are you running ubuntu 13.04 or 12.04? and is your computer 32bit or 64bit? This is important because they will behave differently accordingly. There were some issues with the different versions. If it it is 13.04 it ships with opencv 2.4.2. which according to the opencv website should be enough. Follow the link that I have just included in the video description. if you have any questions.

Hello Francesco,
Thank you for your video above on opencv on ubuntu 12.04. I followed your video to the "t" precisely and the last portion followed Sebastian's site on running the python libraries after the final installation and reboot. Here's what I got by trying to run the Pathon2/turing.py in the directory:
Traceback (most recent call last):
  File "turing.py", line 10, in <module>
    import numpy as np
ImportError: No module named numpy)

PLEASE SEND ME YOUR EMAIL SO THAT I GET SOME FEEDBACK, MOLTO GRACI!!
