This library implements the KLT Tracking algorithm [2004] for Feature Tracking in Video useful in computer vision tasks like object recognition, image indexing, tracking and structure from motion. This implementation uses PROGRAMmable Graphics Hardware to achieve considerable speedup in the running time of the GPU-based implementation.

In this work an implementation of a geometric nonlinear controller for chaos synchronization in a Field PROGRAMmable Gate Array (FPGA) is presented. The Lorenz chaotic system is used to show the implementation of chaos synchronization via nonlinear controller implemented in a Xilinx FPGA Virtex-II 2v2000ft896-4. The main idea is to design a nonlinear geometric controller which synchronizes a slave Lorenz system to a master system and then implement them into the FPGA.

In this paper, a new method is introduced to implement chaotic generators based on the Henon map and Lorenz chaotic generators given by the state equations using the Field PROGRAMmable Gate Array (FPGA). The aim of this method is to increase the frequency of the chaotic generators. The new method is based on the MATLAB® Software, Xilinx System Generator, Xilinx Alliance tools and Synplicity Synplify.

Commercially available active noise control headphones rely on fixed analog controllers to drive "anti-noise" loudspeakers. Our design uses an adaptive controller to optimally cancel unwanted acoustic noise. This headphone would be particularly useful for workers who operate or work near heavy machinery and engines because the noise is selectively eliminated. Desired sounds, such as speech and warning signals, are left to be heard clearly. The adaptive control algorithm is implemented on a Texas Instruments (TI™ ) 1 TMS320C30GEL digital signal processor (DSP), which drives a Sony CD550 headphone/microphone system. Our experiments indicate that adaptive noise control results in a dramatic improvement in performance over fixed noise control. This improvement is due to the availability of high-performance PROGRAMmable DSPs and the self-optimizing and tracking capabilities of the adaptive controller in response to the surrounding noise.
