The three finger salute as used as a sign of revolution as it is in the Hunger Games, does not have a precedence in most cultural popular hand signs or salutes.

- To better define what the salute is supposed to mean, we have to look at it in context.
From Chapter 2 of the first book:
To the everlasting credit of the people of District 12, not one person claps. Not even the ones holding betting slips, the ones who are usually beyond caring. Possibly because they know me from the Hob, or knew my father, or have encountered Prim, who no one can help loving. So instead of acknowledging applause, I stand there unmoving while they take part in the boldest form of dissent they can manage. Silence. Which says we do not agree. We do not condone. All of this is wrong.
Then something unexpected happens. At least, I don’t expect it because I don’t think of District 12 as a place that cares about me. But a shift has occurred since I stepped up to take Prim’s place, and now it seems I have become someone precious. At first one, then another, then almost every member of the crowd touches the three middle fingers of their left hand to their lips and holds it out to me. It is an old and rarely used gesture of our district, occasionally seen at funerals. It means thanks, it means admiration, it means good-bye to someone you love.
After Rue dies:
They’ll have to show it. Or, even if they choose to turn the cameras elsewhere at this moment, they’ll have to bring them back when they collect the bodies and everyone will see her then and know I did it. I step back and take a last look at Rue. She could really be asleep in that meadow after all.
“Bye, Rue,” I whisper. I press the three middle fingers of my left hand against my lips and hold them out in her direction. Then I walk away without looking back.
So Katniss makes this symbol and as the movie shows, the first riots and protests of the uprising against the Capitol begin.
From then on, the significance of the gesture completely changes and it becomes a symbol of the revolution - effectively, a way for the citizens of the Districts to say goodbye to the overbearing force and power of the Capitol. REF: Movie and TV Beta Stack Exchange
It appears the symbol has more to do with revolutionary concepts than its original funerary symbolism and as such it's closest allegory would be the closed and raised fist used by revolutionaries in more modern societies.
