Mat opencv documentation.

The xfopencv library contains enumerated datatypes which enables you to configure xf mat. 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.

For more details on xf mat see the xf mat image container class. Sharing image data between zed sdk and opencv. Cv matx31f matrix 3x1 of float type checking the documentation i saw that most of matrix operations are available but still i don t see the advantages of using this new type instead of the old cv mat. The zed sdk provides its own sl mat class to store image data with a structure and data types similar to opencv cv mat.

In those days the library was built around a c interface and to store the image in the memory they used a c structure called iplimage. I noticed that a new data structure cv matx was added to the new opencv version intended for small matrices of known size at compilation time for example. Image data can be shared between sl mat and cv mat by having the both memory pointers pointing to the same address. The class mat represents an n dimensional dense numerical single channel or multi channel array.
