Maneuvering target tracking is very important in visual surveillance systems. However, as a popular algorithm, the standard interactive multiple model (IMM) filter has imprecise estimation and computerized intractability. To solve the problems, an improved IMM filter is proposed in this work. First, the Kalman filter (KF) and the unscented Kalman filter (UKF) are employed to estimate the non-maneuvering...
In this paper, presented the cause of blocking artifacts and the importance of deblocking artifacts, while explained deblocking artifacts principle. Based on H.264 /AVC standard, the judgement of boundary strength (BS) is specially studied, and proposed an efficient arithmetic for deblocking filter. This efficient arithmetic can improve decoder speed and quality, and shorten about 10% of total time.
