I have error with 'FreeImage_ConvertTo8Bits' with Ubuntu 16.04 OS.

When I do make I got error. I attached the error. It seems it has problem on libfreeimage.so.3 Do you have any solutions?

Sorry, I've never seen this error before. This repo is very outdated. I was using the freeimageplus lib only because opencv didn't support hdr image io back then. I believe the freeimageplus library is poorly maintained, so there's probably some inconsistency. Now that opencv3 supports hdr image io, the simplest solution is probably to replace the 1 or 2 lines in code that uses freeimageplus with opencv equivalents.

@sunweilun Could you refer the code where I should change?

How can I replace this FreeImage?
