... r = 300, skip the transition form of chaotic mapping. Continue to iterate m × n times to obtain 6 chaos matrix codes {X1 }, {X 2 }, {X 3 }, {Y 1 }, {Y 2 }, {Y 3 }. Put {x 7 , a 2 , β 2 , θ 2 }, {x 8 , a 2 , β 2 , θ 2 }, {x9 , a 2 , β 2 , θ 2 }, {x 10 , a 2 , β 2 , θ 2 }, {x11 , a 2 , β 2 , θ 2 }, {x 12 , a 2 , β 2 , θ 2 } into Eq(14) and iterate r times, skip Transition form through chaotic mapping. ...
