I just want to know which kind of data is included in "mat_jf01_Descriptor" returned from the method:

    descExtract.compute(path2Mat(path_jf01), matKeyPts_jf01, mat_jf01_Descriptor);

i created a two nested for-loops and displayed the values, but i do not know what are these values about

I know that, in the following line:

        descripMatcher.match(mat_jf01_Descriptor, mat_jf01_rev_Descriptor, matDMatch);

matDMatch includes distances, but what is included in "mat_jf01_Descriptor"?

match function should have the same parameters as in the docs

So the first parameter (mat_jf01_Descriptor) should contain the descriptors that you are trying to match; the second one (mat_jf01_rev_Descriptor) is containing the descriptors that you trained on (the one that you are searching for) and the third, as you said is containing the distances.

What are the descriptors? They are some values that describe the feature you detected (for more info about how they are computed, see the docs of each type)
