二维图像Fourier全息谱编码显示研究

Research on Fourier Holo-spectrum Encoding Display of Two-dimensional Image

Fourier相位和幅度是二维图像处理中的重要特征,应用于图像压缩编码、信号重构.本文提出Fourier全息谱的理论及编码显示方法,并给出实际显示系统.Fourier全息谱克服了传统的相位谱图显示中出现编码不连续的缺点,并表现了二维图像的Fourier相位特征以及相位与幅度的联系.

Fourier phase and magnitude are two important features of two dimensional image, which have been used for image coding, signal reconstruction. In this paper, theory and encoding display method of Fourier holo-spectrum are presented ,and a display system is developed. The Fourier holo-spectrum overcomes the shortcomings of conventational greyness spectrogram which find it difficult to represent the phase. It displays the Fourier phase and magnitude together, and reflects the inherent relatiorshop between them.
