Hello,
I just installed OpenCV 3.1 with Visual Studio 2013 on Windows 7 (64-bit). Where can I find tutorials running on this version of OpenCV please? Even the official examples do not work, for example: http://docs.opencv.org/3.0-beta/doc/t... returns -1. However, this example works fine: http://docs.opencv.org/2.4/doc/tutori....
Thank you,
Flavien
Use / or \\ instead of \ in your image paths.
To add to the remark of @LorenaGdL, this is OS specific and has nothing to do with OpenCV itself. Windows has a bad habbit of using backslashes as escape characters and thus if you do not use a double slash, you will read C:\opencv\sources\samples\data\HappyFish.jpg as C:pencvourcesamplesataappyFish.jpg, which does not exist. This is because it ignores the characters behind the slashes, since they fall together with official commands for parsing a series of characters.

if the display_image sample returns -1, it simply means, it did not find your image, nothing to do with opencv versions.
maybe you give it another try: just drop an image onto display_image.exe, and it will just work !
http://docs.opencv.org/ <-- pick your choice !
Thank you for your answer.
Yes it can not open the image but even by specifying the path of another image which is located in the same folder, the program does not.
Moreover the original image is in the right place (C:\opencv\sources\samples\data\HappyFish.jpg).
