Cv mat size. The class mat tp is a thin template wrapper on top of the mat class. Thus references or pointers to these two classes can be freely but carefully converted one to another. N dimensional dense array class. Const int cv matsize operator int.

Here are the some popular ones. 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. Multiple images vector of mat can be saved in tiff format see the code sample below. A new matrix of the specified size and specifed type will be allocated.

Size operator const. Nor this class nor mat has any virtual methods. 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. The arrays contained in mv are combined into the output array dst.

Cv merge is the inverse operation of cv split. It does not have any extra data fields. Type has the same meaning as in cvcreatemat. If the format depth or channel order is different use mat convertto and cv cvtcolor to convert it before saving.

The documentation for this struct was generated from the following file. In which mv is a pointer to a c style array of cv mat objects the additional size parameter count must also be supplied. Or use the universal filestorage i o functions to save the image to xml or yaml format. Generated on wed sep 23 2020 03 24 39 for opencv by.

There are many different ways to create cv mat object. Given cv mat named mat. The class mat represents an n dimensional dense numerical single channel or multi channel array. But consider the case where the system has an alignment constraint on the number of bytes per row in the matrix.
