摘要
利用图像高频分量的局部特征,构造一种新的非线性滤波剪切阈值,使整幅图像的增强趋于均匀化、结合平滑去噪和非线性滤波图像增强两个步骤,我们提出了一种实用的MR图像增强算法。试验结果表明增强后MB图像主观视觉效果显著改善。
We have improved the nonlinear filter algorithm employed in image enhancement. Considering the fluctuation of the amplitude of the high frequency component, the new clip strategy improves the performance of image enhancement. Combining the low-pass filter and nonlinear filter, we proposed a new applied MR image enhancement algorithm. The result of enhancement experiment shows that our algorithm is suitable ami powerful.
