Is there two errors about comparative images in this paper?

[angleboy8]

In Fig. 5, the last two images ocurs error. Others images are flipped up and down significantly.

Hi
Fig5 has three groups of comparisons, could you point out which images exactly?

Also, all the results are reproduced by the public code and model. There’s no error in the results.

Hi, the last two groups occur error. You carefully look other eight comparative images except for HR and RCAN one. Others images are flipped up and down significantly. Because of withtout attaching images, I only describe two errors.

Hi,
There's no error. Let's take img_073 in Fig5 as an example. The results of other 8 methods are correct and the exact outputs by their codes and models.
You can run the SR results with other methods to see whether they would produce such results or not. Thanks.

Please you pay more attention the texture direction of fig. Bicubic and fig. RCAN that aren't consistent with fig. HR in the last two groups. Obviously, test image and restoration image in this paper are wrong. If you need my help, I can send you a email that point out the detailed errors.

Ok, please send me an email pointing out the error. yulun100@gmail.com
Thanks!

[angleboy8]

Please notice your email. I just now sent a email. Thank you!

Thank you for your reply. You're right. Indeed, other method exits some drawbacks that produce visual error for people's eyes, which results in my misunderstanding. Thanks a lot again. Best wishes!

The latest version of Pytorch occurs the following error:

The "freeze_support()" line can be omitted if the program
is not going to be frozen to produce an executable.:

    An attempt has been made to start a new process before the
    current process has finished its bootstrapping phase.

    This probably means that you are not using fork to start your
    child processes and you have forgotten to use the proper idiom
    in the main module:

        if __name__ == '__main__':
            freeze_support()
            ...
