最近读到一篇论文，写的很好，但是没有给出源码，于是向原作者写了一封邮件，希望能够要到。
Dear Mr.XXX / Professor XXX,
Thank you for reading!
I am a master of XXX大学 in XXX城市, China.I just took my first step in scientific research focused on Image Super-resolution advised by Prof.XXX in our school.
Recently I read your paper “Efficient Single Image Super-Resolution via Hybrid Residual Feature Learning with Compact Back-Projection Network” published in ICCV 2019. Your clear and compact declaration inspired me a lot. But I got some trouble when I try to implement the algorithm.
I am wondering if you could kindly send me the source code and the necessary information about it. I promise they will be used only for research. I would be very appreciated if you can help me:).
Thank you very much for your kind consideration and I am looking forward to your early reply.
