I have used a program called Pixel Fixer which can learn a profile of each of your cameras and directly process out the dead pixels in the RAW files in a batch operation.

It hasn't been updated in about 8 years so it doesn't necessarily support anything too recent, and is not open source, but I had some success with using it.

Does it support jpegs? Most of the cameras in question don't support RAW output but the problems are individual stuck pixels that are identical between every shot.

Unfortunately it looks like the author only listed the possibility of future JPEG support, but it was not implemented.

Dang. The only thing I've found that comes close is a program called PixelZap, but it hasn't been updated since 2002 and the functionality to purchase the paid version probably just sends your credit info to Russia.
