Trajectory association and clustering are two key problems in motion analysis. While association links the points of interest to form trajectories, clustering discovers motion patterns of these trajectories and group them into clusters. Despite mutually related, the two problems have been typically studied separately in the literature. In this letter, we formulate them as a unified optimization problem...
Multi-rate LDPC codes with near Shannon limit performance are highly demanded in digital television terrestrial broadcasting (DTTB) system. Several proposals have been carried out to construct multi-rate LDPC codes, among which, Row-combining and Row-splitting with Edge Variation (RCSEV) helps construct LDPC codes with constant code length and simple hardware architecture. Besides, Column Extension...
In this paper, we improve the almost blind phase noise suppression method proposed in our recent work and the numerical results show that the system performance can be improved greatly even when severe phase noise exists.
The bar code images captured by camera phone have natural disadvantages in the complex environment, such as blur, low contrast, high brightness, etc. Therefore, it is difficult to decode the bar code successfully without preprocessing. Binarization plays an important role in image preprocessing. In this paper, we regarded time complexity and adaptability under the complex environment as a standard...
