Hardware-software abandoned object detection vision system in heterogeneous zynq device

In this paper a hardware-software abandoned object detection vision system implemented in the Zynq SoC (System on Chip) device is presented. First, the solution was implemented in C++ and run as a bare metal application on the ARM processor core of the Zynq (using floating and fixed-point computations). For the target video stream 1280 χ 720 @ 50 fps (74.25 MHz pixel clock) it reached only 2 fps. Therefore, to speed-up the application, it was decided to move some of the image processing and analysis operations to the programmable logic. This allowed to obtain real-time image processing i.e. 50 fps, with power consumption of less than 4W.
