The HLS video library has been deprecated. All the functions and most of the infrastructure available in HLS video library are now available in AMD Vitis™ Vision, with their names changed and some modifications. These HLS video library functions ported to Vitis vision support build flow.
This section provides the details on using the C++ video processing functions and the infrastructure present in the HLS video library.
All functions imported from HLS video library now take xf::cv::Mat (in sync with Vitis vision library) to represent image data instead of hls::Mat. The main difference between these two is that the hls::Mat uses hls::stream to store the data whereas xf::cv::Mat uses a pointer. Therefore, hls:: Mat cannot be exactly replaced with xf::cv::Mat for migrating.
The following table summarizes the differences between member functions of hls::Mat to xf::cv::Mat.
| Member Function | hls::Mat (HLS Video lib) | xf::cv::Mat (Vitis vision lib) |
|---|---|---|
| channels() | Returns the number of channels | Returns the number of channels |
| type() | Returns the enum value of pixel type | Returns the enum value of pixel type |
| depth() | Returns the enum value of pixel type | Returns the depth of pixel including channels |
| read() | Readout a value and return it as a scalar from stream | Readout a value from a given location and return it as a packed (for multi-pixel/clock) value. |
| operator >> | Similar to read() | Not available in Vitis vision |
| operator << | Similar to write() | Not available in Vitis vision |
| Write() | Write a scalar value into the stream | Writes a packed (for multi-pixel/clock) value into the given location. |
Infrastructure files available in the HLS Video Library hls_video_core.hpp, hls_video_mem.hpp, hls_video_types.hpp are moved to xf_video_core.hpp, xf_video_mem.hpp, xf_video_types.hpp in the Vitis vision Library and hls_video_imgbase.hpp is deprecated. Code inside these files is unchanged except that these are now under xf::cv::namespace.
- Memory Window Buffer
- hls::window is now xf::cv::window. No change in the implementation, except the namespace change. This is located in the “xf_video_mem.h” file.
- Memory Line Buffer
- hls::LineBuffer is now xf::cv::LineBuffer. No difference between the two, except xf::cv::LineBuffer has extra template arguments for inferring different types of RAM structures for the storage structure used. The default storage type is “RAM_S2P_BRAM” with RESHAPE_FACTOR=1. A complete description can be found here xf::cv::LineBuffer. This is located in the xf_video_mem.hpp file.
- OpenCV interface functions
- These functions convert image data of OpenCV Mat format to/from HLS AXI types. The HLS Video Library had 14 interface functions out of which two functions are available in the Vitis vision Library: cvMat2AXIvideo and AXIvideo2cvMat, located in the “xf_axi.h” file. The rest are deprecated.
- AXI4-Stream I/O Functions
- The I/O functions which convert hls::Mat to/from AXI4-Stream compatible data type (hls::stream) are hls::AXIvideo2Mat and hls::Mat2AXIvideo. These functions are now deprecated. Two new functions were added: xf::cv::AXIvideo2xfMat and xf::cv:: xfMat2AXIvideo to facilitate the xf::cv::Mat to/from conversion. To use these functions, the header file “xf_infra.hpp” must be included.
