I've done unit-tests on FPGA implementations of image-processing. Once
you've generated "golden" output files, you just need to check that your
conversions match them - either identity for lossless transformations,
or some RMS/Max-error criteria for lossy transformations (I think YUV
colorspace is better for these checks).  

It's imperfect, but it does catch most of your errors.
