Cubic B-splines is widely applied in non-rigid registration because of its approximation performance and fast computational characteristics. However  a small scale non-rigid deformation is needed to characterize by a large number of control points. Moreover  an iterative optimization strategy of the non-rigid registration algorithm and the normalized mutual information (NMI) cost a great quantity calculation. So  the process of the non-rigid registration is slowed by calculations of NMI in a iterative optimization strategy. In this paper  a parallel optimization algorithm based on cubic B-splines functions is proposed to parallelize the optimization algorithm of the nonrigid registration and the calculations of normalize mutual information. In practice  a fast algorithm of cubic B-splines is used and the control points are only distributed on the targets. Experiments show that the use of the fast algorithm and the parallel optimization strategy improves the non-rigid registration process of medical images. 2011 IEEE.

To the design of an optoelectronic tracking servo system  we test the method [1  not only the reasonability of the control algorithm should be considered  2]. The simulation results verify the theoretical analysis. Because C MEX S function has the features of fast execute speed  but the cost and time as well. It is necessary to establish the simulation model for the system. Applying the C MEX S functions  independently generated program  we can build the every independent digital control modules in MATLAB/SIMULINK for the optoelectronic tracking servo system. In the paper  directly download to the hardwires  we apply the C MEX S function to the design of the practical optoelectronic tracking servo system. For the speed  we can design and debug the digital control modules in MATLAB/SIMULINK and then transform and download directly to DSP processor. 2010 IEEE.  position loop control and TV delay compensations

DirectShow application in LED panel display system (EI CONFERENCE) 会议论文  OAI收割

A new DirectShow application in the field of LED Panel display system is shown in this paper. It realizes video processing functions with DirectShow architecture on computer. Source Filter and many Transform Filters  which provided by Microsoft Co.  transform source video into RGB24 format. Then  the video data are scaled up/down to LED panel resolution by Fixformat Filter which inherite CTramsformfilter baseclass. After that  the R/G/B values of video data are adjusted in CCorrect Filter to adapt LED Panel display. Finally  the processed video is shown on LED Wall through DVI or VGA interface. Our experimental results demonstrate that this system makes a good performance. It is greatly simplify the functions of Sending-Board  Receiving Board  and Control-Scanning-Board in display system of the LED Wall. The total cost will be cut down observably  if we can transplant the filters into the embedded platform  to build a special video processing system for LED Panel display. 2009 IEEE.
