Xilinx devices and Vitis/Vitis AI solutions accelerate many applications, including video processing, image preprocessing, AI inference, memory bandwidth optimization, and more. Let us demonstrate how to develop a human detection application using a Xilinx ZCU104. We show how the Vitis AI stack delivers speed, accuracy and performance, and how to optimize further with Vitis HLS library, DRM, V4L2, and other tools.
