Partial-scrambling of images encoded by JPEG2000 with the parameters that control image quarities and operating tasks

摘要

A method is described for efficient partial-scrambling of JPEG2000 images that avoids generating marker codes and improves the ability to control the degree, strength, and computational complexity of scrambling. This higher control ability is due to the use of a parameter. This parameter also controls the scrambling time, an important consideration for real-time proccessing.
