该文件架下一共有4个matlab程序。结合到一起可以实现在matlab下实现选中ORL库的一幅图像然后找出与之最相近3张照片并显示出来。-the document-a total of the next four Matlab procedures. Can be combined to achieve the Matlab ORL selected under the image of a then identify with the most similar 3 photos and dis

基于＂trace transform＂的识别２Ｄ图像的Ｃ＋＋源程序， 主文件是tt.cpp， 在ＬＩＮＵＸ下可以用 g++ tt.cpp -o tt -O3进行编绎， 而且最后的结果也可以在ＭＡＴＬＡＢ下显示出来， This package presents C++ tools to the trace transform of a 2D image, and related objects, i.e. circuses and triple features, matlab

计算SENSE重建图像中的g-factor,这是并行磁共振成像SENSE算法的关键一步-G-factor is the metric to quantify the amplificaiton of noise power in reconstructing SENSE accelerated image. The detail was presented in Pruessmann s 1999 Magn. Reson. Med. paper. In theory, g-factor is t
