in
Pointer to a MATLAB® struct, mxArray
, having column major data.
The data can be n-channel matrices. Supported data
types:
real_T (double ) | uint8_T (uint8 ) | uint32_T (uint32 ) | int16_T (int16 ) |
real32_T (single ) | uint16_T (uint16 ) | int8_T (int8 ) | int32_T (int32 ) |
copyData
Boolean flag to copy data from mxArray
to the Mat
object.
true
(default) — The function
transposes and interleaves (for RGB images) column major mxArray
data into
a row major cv::Mat
object.
false
— No data copies from
the mxArray
to
the Mat
object. The function creates a new Mat
wrapper
and uses it to point to the mxArray
data. Because OpenCV is row-based
and MATLAB is column-based, the columns of the mxArray
become the
rows of the Mat
object. If the image is 2-D, then copyData
is false
.
out
Reference to OpenCV cv::Mat
with row major
data.
The functions that set copyData
return
an OpenCV smart pointer (cv::Ptr
) to a cv::Mat
object.
The ocvMxArrayToMat_{DataType}
function
applies to two C++ implementations. One set returns void
and
the other set returns an OpenCV smart pointer. The functions that
return void
reallocate memory for the cv::Mat
if
needed.
The ocvMxArrayToMat_{DataType}
transposes
and interleaves column major mxArray
data into row major cv::Mat
.
This matrix conversion is a generic routine for any number of channels.
