非下采样 Contourlet 分解

Question

我有一张图像（医学图像）1024*1024 我正在尝试使用 NSCT 工具箱对其进行分解，但每次我 运行 代码都会收到此错误：

This error was detected while a MEX-file was running. If the MEX-file
is not an official MathWorks function, please examine its source code
for errors. Please consult the External Interfaces Guide for information
on debugging MEX-files.

我使用的唯一 mex 文件是工具箱中的文件

http://www.mathworks.com/matlabcentral/fileexchange/10049-nonsubsampled-contourlet-toolbox

nlevels = [0, 1, 3] ;        % Decomposition level
pfilter = 'maxflat' ;              % Pyramidal filter
dfilter = 'dmaxflat7' ;              % Directional filter

% Nonsubsampled Contourlet decomposition
coeffs = nsctdec( double(im), nlevels, dfilter, pfilter );

Answer 1

我收到这个错误是因为 mex 文件不正确，我的系统是 windows7 64 位，mex 文件是 .mexmac
