Arnold Transformation Algorithm and Anti-Arnold Transformation Algorithm

摘要

Arnold transformation is applied widely in digital image scramble because of its periodicity. But we will waste lots of time when we used its periodicity to get the anti-Arnold transformation algorithm, especially when it used in the picture with big degree. So, in this paper, we use a new anti-Arnold transformation algorithm which got by solving equation groups. By this way, we needn't to figure out the degree, which will save lots of time.
