Analysis of Motion Velocity in Ultrasound Images

In this paper, block-matching with Gaussian Filter adaptive technique is proposed to estimate the motion velocity displacement point in the ultrasound image. We apply the Hexagon-Diamond Displacement Point (HDDP) technique to estimate the motion displacement. The motion displacement is based on the hexagon and diamond displacement pattern search points. The displacement pattern search point is to determine the displacement of motion velocity point in the ultrasound image sequence. The motion velocity displacement point is then used as reference point to access the diagnose or problematic area. Furthermore, motion velocity displacement point will be used as reference point to measure the displacement distance from the original point. At the same time, Gaussian Filter will help to suppress the existing high level of noise in order to improve the point signal-to-noise ratio (PSNR) of the ultrasound image sequence. The experimental result shows that the Gaussian Filter helps to improve the PSNR points in the ultrasound images sequence.
