Recently, a large scale air pollution problems, such as haze and fog bring challenges for target tracking in computer vision. However, most existing tracking algorithms are far from satisfactory in terms of adaptability to complex scenes and restoring the image's quality for hazy scenes. To address this issue, a particle filter based on context tracking algorithm is proposed for real-world hazy scenes...
Packet Classification (PC) is a key functionality for next-generation Internet routers to provide various advanced services. In such high-speed network environment, the accuracy and efficiency of packet classification plays an important role in the development of network. Based on analyzing the characteristics of the real rule set, we propose the Efficient Total Prefix Length-Based Clustering Packet...
At present RFID indoor positioning data visualization methods are simple and the visual effect is not ideal. To solve this problem, a method is put forward, which can make RFID indoor localization algorithms implement in a geographic information system. By overlaying the CAD floor plan with the outdoor maps, every indoor space positioning result has a unique geographic coordinate. To combine RFID...
LEACH (low energy adaptive clustering hierarchy) is one of the popular routing protocols for WSN (Wireless Sensor Network). Cluster head selection algorithm and the inequality of node power consumption are unreasonable disadvantages, thus an energy saving method LEACH-IMP is proposed based on LEACH. All nodes are divided into fixed clusters (In essence, the fixation is relatively). According to the...
In order to enhance the practicality of digital watermarking, watermark perceptibility and robustness must be ensured. Taking human visual system characteristics into account fully, a digital watermarking multi-objective optimization based on multi-wavelet method is proposed. It utilizes Sa4 multi-wavelet to embed digital watermark, chooses intermediate frequency in embedding digital watermark adaptively...
