How to match a drawn Chinese character to a database of stroke animations?

Is this or isn't this a 2 stroke penalty in match play?

• 2 guys were playing in a match head to head. They were paired with 2 other guys to make a 4 - some on a public course. The 2 guys in a match were on the putting green. All 4 balls were on the green. One guy in the match puts and hits one of the balls that's not in the mtach. A 2 stroke penalty and loss of hole was caused due to the player in the match not telling the other guy who isn't in the match to mark his ball on the putting green. What are the rules for hitting a ball that is in a match and isn't in a match on the green from both putting and also the fairway?

• Answer:

  No penalty in match play, even if both balls are on the green. "Rule 19-5a. At Rest If a player’s ball in motion after a stroke is deflected or stopped by a ball in play and at rest, the player must play his ball as it lies. In match play, there is no penalty. In stroke play, there is no penalty unless both balls lay on the putting green prior to the stroke, in which case the player incurs a penalty of two strokes." Under rule 18-5, the ball that was moved needs to be replaced. mt_zion's answer was for stroke play, not for match play
