Function Documentation

template<class T> ImageSet<T> cellArr2ImageSet (  const mxArray *  arrptr  )

convert a cell array of images into an ImageSet Definition at line 496 of file mexConverts.C. References i, and mexFatal().

template<class T> std::vector< ImageSet<T> > cellArr2ImageSetVec (  const mxArray *  arrptr  )

convert a 2d cell array into a vector of ImageSet Definition at line 530 of file mexConverts.C. References mexFatal(), mxGetM(), and mxGetN().

template<class T> mxArray* Image2mexArray (  const Image< T > &  img  )

convert a grayscale image into a mxArray Definition at line 172 of file mexConverts.C. References Image< T >::begin(), conv(), Image< T >::getHeight(), Image< T >::getSize(), Image< T >::getWidth(), height, mxCreateDoubleMatrix(), mxGetPr(), mxREAL, width, x, and y. Referenced by ImageSet2cellArr(), ImageSetVec2cellArr(), mexFunction(), and MexReturn::store().

mxArray* Image2mexArrayUint8 (  const Image< byte > *  img  )

convert a grayscale image into a mxArray of class 'uint8' We take a pointer rather than a reference to ensure that there are no implicit Image type conversions in calls to this function -- we want exactly an Image<byte>, and not an Image<float> or some other pixel type.

template<class T> mxArray* ImageSet2cellArr (  const ImageSet< T > &  imset  )

convert an ImageSet into a cell array of images Definition at line 483 of file mexConverts.C. References i, Image2mexArray(), and ImageSet< T >::size().

template<class T> mxArray* ImageSetVec2cellArr (  const std::vector< ImageSet< T > > &  vec  )

template<class T> mxArray* ImgVec2mexArr (  const ImageSet< T > &  vect  )

convert a vector of pointers to images of equal size into a 3D mxArray Definition at line 364 of file mexConverts.C. References conv(), i, ImageSet< T >::isEmpty(), mexFatal(), mxGetPr(), mxREAL, ImageSet< T >::size(), src, x, and y. Referenced by mexFunction().

template<class T> ImageSet<T> mexArr2ImgVec (  const mxArray *  arrptr  )
