catalogue Enumeration operation Enumeration operation Enumerating supported operations You can use logic, set relationships, and string comparison operations on enumerations. These operations also allow enumerations to be used in conditional statements, such as switch and if statements. The converter can use char vectors and string cell ...

1, Introduction 1 purpose of digital image scrambling So far, the more mature information hiding algorithms basically take the image as the carrier. Image scrambling, as the name suggests, is to disrupt the image and hide the real content of the original image. Digital image scrambling is similar to the idea of information file encryption. It ...
