I'm doing my PhD in computer science and am working in computer vision. I have come up with an algorithm that my supervisors consider to be promising and publishable. It took me a long time to get these results.
Now the thing is that I have to compare my code to other recent papers tackling the same issue. Which I understand is very necessary as to show how my work compares to previous work. My supervisors want me to compare against at least 4 or 5 other recent papers.
The problem is that the database I am using is very recent and no journal papers have till yet used it. So the other solution left for me is to read the journal papers, understand it and try to implement their code.
This will definitely take way too long and in my opinion waste a lot of time. These journal papers are very advanced (obviously) and implementing their results on my own will take up a lot of my time whose only sole purpose is to get a result.
One solution would be to email the authors and ask politely for their source code, but I found out that many authors don't reply.
This question Can I request the code behind a research paper from the author? stated that they were more likely to get a response if they promised to add that author as a co-author in their paper. I do not want to do that as that would be being dishonest as I see no sense in adding the author to my paper just because I compared my work against his, and if I am to compare against 5 papers then that will be a very long list of authors.
Maybe I am asking for something that is frowned upon. Or maybe not asking in the right manner?
I emailed the authors and asked for their code solely to test their work on my database for comparison purposes, which gets no replies. Am I doing something wrong?
