2D-Poisson-Solving

代码中包含在MATLAB中实现DICOM文件的VOILUT感兴趣区域转换。将DICOM文件的数据重新存储为PNG格式的灰度图像。打开一个文件夹的DICOM文件并将其存储在另一个文件夹中以PNG格式储存。(Included in the MATLAB code to implement DICOM files VOILUT region of interest conversion. The data will be re-stored DICOM files in PNG format, grayscale images. Open a folder and stored in the DICOM files to another folder in PNG format.)

实现稀疏表示算法，以lena图像为例，主要用ksvd和omp算法(The sparse representation algorithm is implemented. The Lena image is taken as an example, mainly using the ksvd and OMP algorithms.)

实现图像的Contourlet变换，显示图像变换后每一层的图像。(Realize the Contourlet transform of the image , each layer of image is displayed after transform.)

读取raw图，并转换为rgb图，显示转换后的rgb图(Figure raw read and convert rgb showing the converted diagram rgb)

主分量分析对SAR图像目标进行特征提取，用最近临方法进行分类(Principal component analysis（PCA） of SAR image target feature extraction, classification using nearest-neighbor method)

加入乘性噪声和椒盐噪声的图像进行维纳滤波和均值滤波，采用不同窗口看效果(Add the image of multiplicative noise and salt and pepper noise for Wiener filtering and mean filtering, using different windows to see the effect)

修改过的pca-sift程序 可以正常运行(Modified pca-sift program runs)

OPENCV做图像变形的经典代码啊，适合比较初级的同学看看(OPENCV do image warping the classic code ah, suitable for elementary students to see more)

复杂背景下文字分割程序的源代码，可以很好的对文字进行分割(Text Segmentation in Complex Background program' s source code, can be a good segmentation of text)

这是三维点云数据边缘线提取的c++算法，适合于LIDAR数据的三维处理，供大家参考学习(This is 3 d point cloud data edge extraction of c++ algorithm, suitable for LIDAR data 3 d processing, provide everyone reference to study)
