Difference between two folders

[wrldwzrd89]

Is there a simple way (i.e. 100% free, including using the Terminal) to determine which files in one folder are NOT in another, disregarding any extensions the files in each folder have?

One way I thought I could approach this, using the Terminal:

ls /path/to/first/folder > folder1.txt
ls /path/to/second/folder > folder2.txt
diff folder1.txt folder2.txt

Only problem is that this does NOT ignore extensions, so all the lines in both text files will be reported as different. This is NOT what I want.

So, for instance, if you have a hayguys.jpg in one folder and a hayguys.gif in the other folder, you want them to be recognized as the same file, correct?

I'm a grep novice, but is there a way you can use grep and/or regex to do it? I know I've seen scripts that strip file extensions before, like this discussion here:

It should not be too hard to modify them for your purpose.

Yes, exactly. This is because I'm mass-converting files from one format to another, and I want to find the files that didn't convert properly. Thanks!
