All Vitis vision library functions follow a common format. The following properties hold true for all the functions.

• All the functions are designed as templates and all arguments that are images, must be provided as xf::cv::Mat.
• All functions are defined in the xf::cv namespace.
• Some of the major template arguments are:
  • Maximum size of the image to be processed
  • Datatype defining the properties of each pixel
  • Number of pixels to be processed per clock cycle
  • Depth of the hls::stream defined in xf::cv::Mat
  • Other compile-time arguments relevent to the functionality.

The Vitis vision library contains enumerated datatypes which enables you to configure xf::cv::Mat. For more details on xf::cv::Mat, see the xf::cv::Mat Image Container Class.
