The traditional highway toll system identification algorithm which is only based on license plate is not accurate. It results that the evading toll fee behavior is difficult to prohibit. To solve the above problems, a new method based on vehicle appearance feature points was proposed. Firstly Haar feature and Adaboost classifier were adopted to detect vehicle, and the ORB algorithm was used to detect...
With the rapid development of Internet and cloud services, logs become one of the fastest growing data types in backup storage systems. These massive data always require long-term storage, which incurs high storage overhead. Typical compression algorithms, such as traditional lossless compression and log-specific compression algorithms, are employed to increase storage efficiency. However, these algorithms...
The Kalman filter has been found to be useful in vast areas. However, it is well known that the successful use of the standard Kalman filter is greatly restricted by the strict requirements on a priori information of the model structure and statistics information of the process, and measurement noises. Generally speaking, the covariance matrix of process noise is harder to be determined than that...
The detection of cracks on solar panel surfaces is the most important step during the inspection of solar panel, and it has very important practical significance. Recently some automated crack detection techniques that utilize image processing have been proposed. But these methods costs lots of computation time and didn't get a high accuracy. Aiming at some problems of the existing algorithm, we proposed...
In this paper, we present a closed labeled tree mining algorithm, FBMiner, based on the add-remove principle of closed sets which is newly introduced. Also, we propose a time-decay module to solve stream data mining which gives more attention on the latest data. Compared to the traditional mining algorithms in data stream, FBMiner performs well even that the data is of high complexity. The experiment...
In this paper we indicate the concept of dynamic data flow graph based on the dynamic data dependency during execution of software. On this basis, we propose a dynamic software watermarking algorithm, which embeds watermarking information into DDFG of software, and discuss the implementation of embedding and extracting watermark. Finally we analyze the performance of this algorithm.
