Phase preserving Fourier descriptor for shape-based image retrieval
作者：
Highlights：
• Magnitude-based Fourier descriptors discard information contained in phase.
• Invariant phase-preserving Fourier descriptor is proposed.
• Pseudomirror points are introduced, and used as shape orientation references.
• The proposed descriptor is compact, effective and simple to extract and compare.
• Retrieval performance is improved without increasing computational complexity.
