FPGA implementation of real time digital video stabilization

Özsaraç, İsmail
Video stabilization methods are classified as mechanical and digital. Mechanical methods are based on motion sensors. Digital methods are computer programs and classified into two as time domain and frequency domain based on the signal processing methods used for the motion analysis. Although, mechanical methods have good real time stabilization performance, they are not suitable for small platforms such as mobile robots. On the other hand, digital video stabilization methods are easy to implement on various hardware, however, they require high computational load and long processing time. Two different digital video stabilization methods, one frequency and one time domain algorithms, are implemented on FPGA to realize their real time performances. Also, the methods are implemented and tested in MATLAB. FPGA results are compared with MATLAB’s to see the accuracy performance.The input video format is PAL of which frame period is 40ms. The FPGA implementation is capable of producing new stabilization data at every PAL frame which allows the implementation to be classified as real time. Also, the simulation and hardware tests show that FPGA implementation can reach the MATLAB accuracy performance.
