摘要

提出了一种基于傅里叶相位校正的图像边缘锐化技术。这里的技术包括传统的(拉普拉斯算子)和校正傅里叶相位的纯相位合成。为了保持图像灰度的自然平滑性，还引入了人的视觉属性作为加权函数。仿真实例表明，该方法比传统方法具有明显的优越性。

The effect of the observation Fourier sign correction for image sharpening

An image edge sharpening technique with Fourier phase correction is presented. The technique here includes a traditional one (Laplacian operator) and phase-only synthesis with the corrected Fourier phase. A human visual property is also introduced as a weighted function in order to maintain the natural smoothness in the gray level of the image. Simulation examples show that the proposed technique is much superior to the traditional one.
