some questions about the code of "Color image zero-watermarking based on Fast Quaternion Generic Polar Complex Exponential Transform"

Dear author,
I am a university college student. May I ask some questions about the code of "Color image zero-watermarking based on Fast Quaternion Generic Polar Complex Exponential Transform"?
After running the code, I found the result is not the color image. So I replace the color image, but the result is not been changed. Besides, can other pictures of results in the paper "Color image zero-watermarking based on Fast Quaternion Generic Polar Complex Exponential Transform" be provided only by MATLAB such as security test and so on. Do I need any other operation?
Hope to your reply. Thanks a lot.
