前言：目的：利用衍射增强成像(DEI)技术成像机制的特异性，进行医学样品的成像研究，并进行分析评价。
Objective: With the exceptionally excellent, DEI is used to image on medical samples and the imaging result is evaluated.
由于超声成像机制的限制，图像质量相对较差一直是超声医学图像主要的缺点，难以满足后期的图像分析工作的要求。
In view of speckle noise in medical ultrasound image, adenosing method based on adaptive morphological filter was proposed.
SAR的后向散射成像机制决定了SAR图像中存在相干斑噪声，这些相干斑噪声降低了图像质量，掩盖了图像的细节结构，因此在SAR图像处理时通常先对图像进行去噪。
Because of the backscatters, SAR images are contaminated by speckle noises which lower image quality and mask image structure. Therefore, noise-smoothing is the first step in the image processing.
