[Graph programefficient_registration

Description: 利用傅里叶变换,在频域上对两幅图像配准,是一种比较配准的新方法,但是对弹性配准的效果不是很好 需要进一步的研究。-Registers two images (2-D rigid translation) within a fraction of a pixel specified by the user. Instead of computing a zero-padded FFT (fast Fourier transform), this code uses selective upsampling by a matrix-multiply DFT (discrete FT) to dramatically reduce computation time and memory without sacrificing accuracy

[matlabbackproj

Description: BACKPROJ uses the filtered or unfiltered backprojection algorithm to perform the inverse Radon transform. The filter is designed directly in the frequency domain and then multiplied by the FFT of the projections. The projections are zero-padded to a power of 2 before filtering to prevent spatial domain aliasing and to speed up the FFT.-BACKPROJ uses the filtered or unfiltered backprojection algorithm to perform the inverse Radon transform.

[2D Graphicndnanfilter

Description: NDNANFILTER N维零相位数字滤波器,忽略NaN的。 短语法: [年,钨] = ndnanfilter(十,HWIN,女) 短输入: X - 有/无NaN的多维数据。 HWIN - 窗口的名称(默认情况下移动平均的Nd: rectwin )。 的F - 向量指定为每个维窗口半宽度。 短暂输出: Ÿ - 过滤/平滑X数据与零相移(如X!一样大小)。 W - N维是通过一种特殊的子函数生成的中心对称的窗口称为NDWIND。 简短描述: 此功能适用于一对X与W N维卷积,利用MATLAB的IMFILTER或CONVN功能,忽视/插值/灌装NaN的。 默认情况下,边缘与在与PADARRAY MATLAB的函数的边界的X值填充。当PADARRAY没有找到,该程序执行零填充。 简短说明: *见截图。-NDNANFILTER N-dimensional zero-phase digital filter, ignoring NaNs. SHORT SYNTAX: [Y,W] = ndnanfilter(X,HWIN,F) SHORT INPUT: X- Multidimensional data with/without NaNs. HWIN- Window s name (N-D moving average by default: rectwin ). F- Vector specifying the semi-width of the window for each dimension. SHORT OUTPUT: Y- Filtered/smoothed X data (same size as X!) with zero phase shift. W- N-dimensional window with central symmetry generated by a special subfunction called NDWIND. SHORT DESCRIPTION: This function applies a N-dimensional convolution of X with W, using the MATLAB s IMFILTER or CONVN function, ignoring/interpolating/filling NaNs. By default, the edges are padded with the values of X at the borders with the PADARRAY MATLAB s function. When PADARRAY is not found, the program performs zero-padding. SHORT NOTE: * See the screenshot.
