In this paper, an occlusion handling algorithm is presented for motion-compensated frame interpolation (MCFI). The proposed algorithm first estimates the unidirectional motion vector fields (MVFs) between two reference frames in both forward and backward directions. Then, a multiframe-based occlusion detection method is presented to identify the uncovered, covered, and motion ambiguity regions within...
In this paper, we study how to use semantic relationships for image classification in order to improve the classification accuracy. We achieve the goal by imitating the human visual system which classifies categories from coarse to fine grains based on different visual features. We propose an ontological bagging algorithm where most discriminative weak attributes are automatically learned for different...
Multilateration (MLAT) surveillance is now being used in all types of airspace for air traffic management. MLAT can be used for airport surface movement surveillance as well as for terminal and en route surveillance, using Wide Area Multilateration (WAM). MLAT is a low-cost technology that not only has major advantages in operations and maintenance, but also provides excellent performance under all...
Influence on Strapdown Inertial Navigation System (SINS) error characteristics for different IMU (inertial measurement unit) rotation schemes was analyzed theoretically.It's indicated that, in single-axial and single-directed rotation scheme the gyro's bias on rotational axis was not modulated, but a equivalent bias calculate by scale-factor error multiplying rotating velocity was introduced in rotational...
