matlab实现源阈值去噪

利用蝶形算法，实现快速傅立叶变换及其逆变换-The use of butterfly algorithm, fast Fourier transform and its inverse transform

空域像素级直接图像，规则简单 易于实现 但是效果有限 附图片-Direct class airspace pixel images, the rules of simple easy to achieve but a limited effect

这是我本科的毕业设计做的关于医学图像的基于形状的图像检索。预处理用小波去噪 ，特征选用不变矩。-This is my undergraduate graduation design done on the medical images based on the shape of the image retrieval. Pretreatment with wavelet denoising, feature selection invariant moment.

图像分割常用的主动轮廓模型中的一个经典算法――贪心算法的C++实现-Image segmentation of the active contour model commonly used in a classic algorithms- greedy algorithm C++ Achieve

用于实现相机的自动调焦，里面又自己定义的调焦函数，利用清晰度评价的方法去调焦。用于实际的工程运用。-Used to implement auto-focus camera, which has its own definition of focusing function, the use of evaluation methods to focusing clarity. Used in actual engineering applications.

This collection of m-files will only get you through the very bear necessities (Look for the ...) of a single-run fMRI-analysis. Its actual aim is to illustrate the efficacy of spatial regularisation of the autocorrelation esimate in the framework of prewhitening the data to correct for serial correlations in the data, as described in the following paper: Gautama, T. and Van Hulle, M.M. (2004), Optimal Spatial Regularisation of Autocorrelation Estimates in fMRI Analysis, NeuroImage, in press.

通过小波变换提取图像亮度，模糊度和相关度等多项指标综合表示图像质量，达到真正的自适应。-Extracted through the wavelet transform image brightness, degree of ambiguity and that a wide range of image quality index, the true adaptive.

数字识别 我初学者 希望能大家喜欢我上传得-digital identification beginners I hope everyone likes me in behind the upload

delphi图像处理 It was developed using Delphi 5 Pro, but it should work OK with D4 or even D3. It uses 24-bit bitmaps and scanline for speed. I have included the text version of the two forms, hopefully it will enable people with D3 or D4 to use this example.-delphi image processing It was developed using Delphi 5 Pro, but it should work OK with D4 or even D3.
