医用图像处理程序,处理dicom文件。开源软件,参考dcmtk(dicom process soft)

基于对尺度的MSR算法的医学图像增强算法。 调试可以通过 对于低对比度的医学图像有很好的效果！(scale based on the MSR algorithm of medical image enhancement algorithms. Debugging through the low-contrast image has good results!)

多聚焦图像融合，将两张到六张不同焦点的图片合成成一张。(Multi-focus image fusion, will be the focus of two to six different images into a synthesis.)

提出一种基于空间域的多聚焦图像融合技术：首先计算点分布函数（PSF），然后利用PSF模糊源图像，最后通过组合原图像中较为清晰的像素点来生成全聚焦图像。(We propose a multi-focus image fusion based on space domain techniques: First calculate the point distribution function (PSF), then use the PSF fuzzy source image, and finally to generate omni-focus image by combining the original image clearer pixels.)

理解频域处理与空间域处理的等效关系与步骤，掌握频域相乘与空间域循环卷积之间的对等关系，理解DFT运算中补零的效果。(Understand the equivalent relationship and steps of frequency domain processing and space domain processing, understand the reciprocal relationship between frequency domain multiplication and space domain circular convolution, and understand the effect of zero padding in DFT operation.)

本算法实现了dct基字典的构造并用其进行对图像的消噪。(Algorithm DCT-based dictionary structure and use it for image de-noising.)

说明：  实现图像受混合噪声污染时去除噪声的目的，在6种方法比较之下，得出最优的图像去噪算法(Image by mixed noise pollution when the purpose of removing noise, in the six kinds of methods of comparison, the optimum image denoising algorithm)

说明：  给图像加扰动，扰动方式以zernike多项式的形式加入，Image为源图像，Co为要加的zernike系数，为行向量， 输出分别为扰动后的图像，扰动PV值，扰动RMS值(failed to translate)
