加权中值滤波，用于图像增强，只用于超声图像，对超声图像去噪有很好的效果。内还包括信噪比计算方法。-weighted median filter for image enhancement, only for ultrasound images of ultrasound image denoising with very good results. Which is also a signal-to-noise ratio calculation.

自适应区域直方图均衡，用于图像增强，适用于超声图像，对超声图像的灰度增强又很好效果。-regional adaptive histogram equalization for image enhancement applies to ultrasound images, Ultrasound images of the Gray also enhanced good results.

完成基于各向异性的自适应超声图像去噪和边缘增强方法，参考Adaptive Anisotropic Diffusion for Ultrasonic Image Denoising and Edge Enhancement.pdf，加入了m参数,The completion of ultrasound-based adaptive anisotropic image denoising and edge enhancement method, reference Adaptive Anisotro
