摘要 ：
This work presents the deep learning networks-based method using fine-tuning for classification and search of a diversity of action videos. First, a 3D convolutional neural networks (3D CNN) model which performs pre-training operation and fine-tuning strategy is employed to extract the spatiotemporal features of videos. It is first pre-trained on UCF-101 datasets to train model with initial parameters. Then, a small new dataset is employed to fine-tune the initial model for the training of the new model. Once features are extracted by the final CNNs model, distance measure can be adopted to calculate the similarities between the query video and the test dataset for the video search. The searched video is returned and ranked according to the priority when it has higher similarity with the query video. The comparison results in the experiment shows that the search method using fine-tuning obtains better performance than the method without using fine-tuning. Second, the classification results based on the 3D CNN model using fine-tuning are also presented for the consideration of a query by keyword. Accuracy result obtained using the model with the help of fine-tuning is approximately 2.8% higher than that without using fine-tuning.

摘要 ：
To reduce DMA utilization for multiple algorithm IPs on FPGA, a channel configurable and multiplex DMA device (CMDMA) is proposed for asynchronous and heterogeneous algorithm IPs. Firstly, we abstract the entities and data-flow in CMDMA system with a formal description for function definition and work-flow analysis. Then based on the functions and work-flow, we design and implement a prototype of CMDMA, which includes CMDMA software driver (SW) and hardware circuits (HW) of one DMA IP, a configurable input switch (CISwitch), algorithm IPs, and an asynchronous output switch (AOSwitch). The configurable function of CMDMA is implemented by CISwitch through a configuration port in HW-level, and a configurable Round-Robin (CRR) algorithm is proposed to implement channel and input data schedule in SW-level. For output, a channel distinguishable output buffer (ChnDistBuf) is proposed, which is able to deliver channel ID and data size to SW earlier than the end time of an algorithm IP. With a double interrupt coordination method of both ChnDistBuf and algorithm IPs, CMDMA is able to successively store complete output data from different algorithm IPs. With a double interrupt coordination method of both ChnDistBuf and algorithm IPs, CMDMA is able to successively store complete output data from different algorithm IPs. The experiments based on 4 heterogeneous matrix multiplication algorithm IPs on Xilinx Zynq platform show that CMDMA is able to improve about 8% 29% average algorithm acceleration rates on single algorithm IP compared to the exclusive method that one DMA works for one algorithm IP only, and it is able to increase about 10-40 MB/s and 5-15 MB/s of DMA input and output data throughput with multiple algorithm IPs running in parallel. Moreover, the extended LUT and FF resources in CMDMA are 756 and 1219 , both of which are about 1% of Zynq platform. Besides, in a double CNN algorithm IPs test on Mnist application, an enhanced function of data broadcasting in CMDMA is able to improve 4 s than the system with 4 exclusive DMA running in parallel, meanwhile reduce 3 DMA utilization and 0. 03 W power consumption.

摘要 ：
一种面向边缘端行人跟踪和人数精确统计的方法，涉及边缘计算场景下基于人工智能部件的行人跟踪和人数统计领域。该方法初始时建立并实时维护行人动态跟踪列表。从边缘端的人工智能部件获取行人结果信息，并在其基础上建立行人静态检测列表。将行人静态检测列表和行人动态跟踪列表进行精确匹配。边缘端的成本及性能限制使得边缘端计算能力有限会导致行人精确匹配失败。此时，该方法将根据行人动态跟踪信息对行人进行智能模糊匹配。根据匹配后的结果实时更新行人动态跟踪列表，并对统计区域内的行人进行人数精确统计，若精确统计失败，所述方法对该行人使用延迟计数策略。

摘要 ：
RFID is one of the indispensable technologies employed to implement the Internet of Things, where it facilitates the identification and awareness of objects in our daily lives by integrating backscatter tags. The interference synthetic aperture radar (InSAR)-based localization scheme provides high precision in 3-D conditions, although it still has some practical problems such as its strict sampling operation and it is also highly time consuming. In this article, we developed E3DinSAR as an optimized InSAR-based 3-D localization approach for pinpointing tags rapidly and easily with high accuracy. E3DinSAR does not use any other infrastructure or reference tags, and only one movable reader with one antenna is sufficient to implement the localization method, where it measures the phase value of the tag at different positions throughout its movement in order to create multiple holographic images. In contrast to the previously proposed InSAR-based technique, we extend the sampling trajectory of the reader to an arbitrary curve by restricting it to several approximate linear apertures, which allows more flexible operations and increase the accuracy. We also employ a rapid computing method to calculate the results for the holographic images by estimating the direction of arrival for the tag. Experiments were performed where E3DinSAR was implemented with commercial off-the-shelf (COTS) RFID products and our systematic evaluation showed that E3DinSAR achieved a mean locating accuracy of 18.4 cm in a 3-D space.
