The Vitis Vision library is a set of select OpenCV functions optimized for Zynq-7000, Zynq UltraScale+ MPSoC, Versal VCK190, Alveo U200 and U50 devices. The maximum resolution supported for all the functions is 4K, except Houghlines and HOG (RB mode).
Important
All the functions in the library are implemented in streaming model except 7. Bounding box, Canny, Cornertracker, Crop, EdgeTracing, MeanShiftTracking, Rotate are memory mapped implemenations. These functions need to have the flag __SDA_MEM_MAP__ set for compiling correctly
Important
Default depth value for all the memory mapped implemenations(Bounding box, Canny, Cornertracker, Crop, EdgeTracing, MeanShiftTracking, Rotate) is “_XFCVDEPTH_DEFAULT = -1”. Default depth value for all the streaming model implemenations is “_XFCVDEPTH_DEFAULT = 2”.
Note
Number of pixel per clock depends on the maximum bus width a device can support. For example: Zynq-7000 SoC has 64-bit interface and so for a pixel type 16UC1, maximum of four pixel per clock (XF_NPPC4) is possible.
