block iteration
解釋
塊迭代-
Conclusion r1 represent pixel - value of original image range block, r represent mean - value of original image range block, d represent mean - value of original image domain block, d1 represent pixel - value of resumptive image domain block, d represent mean - value of resumptive image domain block. superior perfermance of resumptive image range block is obtained as compared to conventional creative function by one iteration, that is,
） ， d _ i （ i = 1 ， 2 ， … ， n ）分別為某一恢復圖像定義域塊的均值和每一像素的像素值，我們用傳統的和改進的生成函數分別進行一次迭代，則用改進的生成函數進行迭代的恢復圖像每一值域塊的效果較好，即： -
Listing 6 shows an example of such an approach, which nests the try - catch block inside the iteration loop
）清單6顯示了這種方式的一個示例，它在迭代循環內部嵌套了try - catch塊： -
Abstract aiming at the defects of diffusion function with lower diffusing speed and needing multiple round iteration to resist differential attack in the image encryption algorithm based on chaotic block cipher, a new chaotic image encryption algorithm based on output ? cryptograph mixed feedback was proposed
摘要針對現有基於混沌分組密碼的圖像加密演算法中，擴散函數擴散速度慢、需要多輪迭代才能抵抗差分攻擊的缺點，提出了一種新的基於密文和輸出混合反饋的混沌圖像加密演算法。 -
