摘要
在彩色图像超复数二维傅里叶变换方法的基础上,提出了基于四元数傅里叶变换方法对彩色图像在频域内进行降噪和增强处理,先利用高斯带通滤波器对彩色图像在频域内进行滤波,然后再通过四元数傅里叶逆运算获得滤波后的图像。仿真实验结果表明,该算法对彩色图像去噪具有良好的效果。
The computing of the hypercomplex 2-D Fourier Transform of a color image as a whole unit has only recently been realized.It was concerned in this paper with frequency domain noise reduction of color images using quaternion Fourier transforms.The approach was based on obtaining quaternion Fourier transform of the color image and applying the Gaussian filter to it in the frequency domain.The filtered image was then obtained by calculating the inverse quaternion Fourier Transforms.Experiment results showed that this method performs well in noise reduction of color images as a powerful tool in color image texture and pattern analysis.
