Algorithm Architecture Research And Implementation Of Gesture Recognition And Tracking System Based On FPGA

Non-contact human-computer interaction is an emerging field, and the algorithm has made considerable progress in the recent years. It is a trend that using gestures for remote control of household appliances and other equipment, which enriches the interaction between humans and machines to some extent, while providing a well user experience. However, most of the existing non-contact system is based on interactive software platform, and the platform-independent cause the slow process of its commercialization. The main work of this paper is to design an interactive system which does not rely on software platform, and the system provides a useful exploration in commercialization of non-contact system. There are some exploration in image processing based on FPGA at home and abroad, but most are still in its infancy. The topic will provide a transitional produce of non-contact interactive system based on designing the improvement and the hardware configuration of algorithm and other aspects.This paper will propose a set of real-time optimization and complexity, low power solution by studying the human-computer interaction in complex background, and complete the interactive system based on hand detection, tracking, which dose behavioral modeling by using Verilog HDL language and making full use of the characteristics of FPGA parallel processing. The system uses DE4-230 provided by Altera as simulation platform and verifies the availability and timeliness by using the dimensional camera and VGA monitor. The main work includes three aspects. The firstly, to design the controller to ensure the system performance and cost minimizing resource. The secondly, analyzing the global and local system timing to improve robustness of the system. Finally, optimizing the interactive algorithm to meet the performance and real-time requirements.This paper explores the image processing algorithms chips, and combined the software algorithms and hardware parallelism. The advantage of FPGA is fully taken, and the process of commercialization of touch-less HCI chips is promoted...
