Local quaternion polar harmonic Fourier moments-based multiple zero-watermarking scheme for color medical images
作者：
Highlights：
• This scheme is the first multiple color medical image zero-watermarking scheme.
• It constructs multiple zero-watermarks and effectively improves the reliability.
• It does not change the original image, and ensures image integrity.
• It can resist complex desynchronization attacks such as cropping and Unzign, etc.
• It has better performance than state-of-the-art multiple watermarking schemes.
