Cv mat size.
It does not have any extra data fields.
In which mv is a pointer to a c style array of cv mat objects the additional size parameter count must also be supplied.
It can be used to store real or complex valued vectors and matrices grayscale or color images voxel volumes vector fields point clouds tensors histograms though very high dimensional histograms may be better stored in a sparsemat.
A new matrix of the specified size and specifed type will be allocated.
Dst output array of the same size and the same depth as mv 0.
The class mat represents an n dimensional dense numerical single channel or multi channel array.
There are many different ways to create cv mat object.
This will work in conventional scenarios where the matrix was allocated as a contiguous chunk in memory.
The arrays contained in mv are combined into the output array dst.
The documentation for this struct was generated from the following file.
Type has the same meaning as in cvcreatemat.
Const int cv matsize operator int.
Size operator const.
Nor this class nor mat has any virtual methods.
Size t sizeinbytes mat total mat elemsize.
C mat vec uchar n abs a alpha beta is equivalent to convertscaleabs a c alpha beta the output matrix has the same size and the same type as the input one except for the last case where c is depth cv 8u.
Cv merge is the inverse operation of cv split.
But consider the case where the system has an alignment constraint on the number of bytes per row in the matrix.
Here are the some popular ones.
Given cv mat named mat.
If the format depth or channel order is different use mat convertto and cv cvtcolor to convert it before saving.
Multiple images vector of mat can be saved in tiff format see the code sample below.
N dimensional dense array class.
Using cv mat create nrows ncols type method or the similar constructor cv mat mat nrows ncols type fill value constructor.
