Cv Mat Size

Nor this class nor mat has any virtual methods.

Cv mat size.

Const int cv matsize operator int. N dimensional dense array class. Multiple images vector of mat can be saved in tiff format see the code sample below. Size t sizeinbytes mat total mat elemsize.

Thus references or pointers to these two classes can be freely but carefully converted one to another. The class mat tp is a thin template wrapper on top of the mat class. 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. A new matrix of the specified size and specifed type will be allocated.

This will work in conventional scenarios where the matrix was allocated as a contiguous chunk in memory. Using cv mat create nrows ncols type method or the similar constructor cv mat mat nrows ncols type fill value constructor. In which mv is a pointer to a c style array of cv mat objects the additional size parameter count must also be supplied. The class mat represents an n dimensional dense numerical single channel or multi channel array.

Or use the universal filestorage i o functions to save the image to xml or yaml format. It does not have any extra data fields. 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. Cv merge is the inverse operation of cv split.

There are many different ways to create cv mat object. 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. The arrays contained in mv are combined into the output array dst.
