Abstract: On the basis of computer automatic control theory of artificial intelligence, we use Kmeans clustering algorithm to establish mathematical model of automatic art synthesis for computer painting, and realize the computer artificial intelligence painting synthesis by using MATLAB software. In the first part we introduce the intelligent control system of computer drawing in detail, and do decomposition and combination on the frame number by using the computer intelligent drawing cell.

Abstract: From rest to exercise and from two-dimensional to three-dimensional, digital image processing software can be multi-angle, multi-dimension, multi-direction infiltration for the various fields of design, which has wide applications in every corner of digital media. Firstly, the digital image processing software can analyze the common digital processing system model. On the basis of the principle of RGB color histogram, it also can analyze its application in the ceramic design. According to the set of image transformation principle, the analysis of the geometric transformation plays an important role in in ceramic set, to provide the theoretical basis for the digital image processing software to a certain extent.

Abstract: In this article, a design of multi-channel data acquisition system is presented. With FPGA as the core controller, the system can implement logic control over the high-speed ADC and acquire high-speed and high-resolution sample data. Using asynchronous FIFO as a cache, it can transfer data between two different clock domains: ADC data acquisition module and RS485 data module, which helps to improve the work efficiency and data throughput of the system. In the Quartus II development platform, Verilog hardware description language is adopted and finite state machine so that parallel acquisition operation to multi-channel ADC controlled by FPGA can be achieved and the system can become equipped with high-resolution, strong real-timeliness, low noise interference and other advantages. When it comes to the final step, simulation of AD sampling, asynchronous FIFO and RS485 transmission are conducted under the Modelsim environment and on-line testing by Signaltap to the system is synchronously implemented. The validity and reliability of the system are verified.

Abstract: In this paper, we proposed a regularized particle filter (RPF) algorithm for multi-user detection (MUD) in synchronous code division multiple access (CDMA) system. It is especially suitable for non-linear non-Gaussian system. In the standard particle filter algorithm. If particles weights have vast difference, we needed to re-sampling, but it replicates particles with larger weights and discards particles with small weights, so that it will lose the diversity of particles. Regularized particle filter algorithm can effectively overcome this shortcoming.

Abstract: This paper presents an effective encoding technique for super FEC. By using the pre-coding technique, the encoder can process data segmentally and can be multiplexed by multiple data coming from different code words, reducing the storage space of payloads and latency. A concatenated BCH encoder using this improved encoding technique has been designed and realized in FPGA. Simulation results show that the data rate can be up to 10Gbps under the working frequency of 156MHz and the memory usage and processing latency are significantly decreased

Abstract: The application of mobile ECG detection plays an important role in finding out what the heart conditions are. It will prevent and treat the cardiovascular disease. At present, it is hard to exchange the information in various heterogeneous systems. HL7 standard specifies the medical information transfer format, and improves the degree to share the data among the medical information systems. Based on HL7 standard and web service technology, this paper designed HL7 engine to realize the seamless data transfer among the heterogeneous systems, and enable sharing and interaction of ECG information, as well as improve the working efficiency and competitiveness of medical system.

Abstract: Photogrammetric calibration methods for digital CCD cameras are usually capable of acquiring explicit distortion parameters. However, it would cause the correcting results to be less accurate due to irregular array with explicit image correction method. In order to produce images with less distortion, an implicit model was proposed in this paper. Moreover, the model was applied to correct images from a non-metric camera. The real tests with images indicate the improvement is more obvious in eliminating distortion on images.
