Hi Gabriel,
one problem is the 'blobs.gif' file - if ImageJ opens that from ImageJ/samples/blobs.gif via an 'open' command, the image has no inverted LUT (as it should have) but the same appearance, thus different pixel values. In that case you get 'fail' messages for every test.
If it opens 'blobs.gif it via File>Open Samples, it has the correct LUT and pixel values.
Thus, in the macro, you should have the 'blobsFile' variable not pointing at the location where it can fine 'blobs.gif'. As we have the possibility of caching sample images in ImageJ now, the macro code to directly read the image is obsolete anyhow.
Apart from that problem, I got no error, neither with 1.49e1 nor with 1.49e12.
(OS X 10.6.8, Java 1.6.0_65 [64-bit])
Your other error message looks strange:
> FAIL: Smooth: type=8bit select=all nThreads=1, single image: mean=63.34
> expected=62.8975
This means that the simple "Smooth" command does something wrong on your machine!
Process>Smooth should have exactly the same result as Process>Filters>Mean with a radius of 1 pixel, but it uses the ImageProcessor's 'smooth' method instead of the RankFilters.
Could you please try the two commands and see whether there is any difference between the results, and if so, what went wrong?
Michael
