Aiming at the problems of long registration time and low registration accuracy of current image registration algorithms,an image registration algorithm based on Grid-based Motion Statistics(GMS),Vector Coefficient Similarity (VCS)and Graph-Cut RANdom SAmple Consensus(GC-RANSAC)was proposed. Firstly,the feature points of the image were extracted through the ORB(Oriented FAST and Rotated BRIEF)algorithm,and Brute-Force matching of the feature points was performed. Then,the coarse matching feature points in the image were meshed by the GMS algorithm,and the coarse matching pairs were filtered based on the principle that high feature support exists in the neighborhood of the correct matching points in the grid. And the part elimination was performed to the matching pairs by introducing the principle that the image matching pair has VCS not exceed a set threshold during vector operation,which is beneficial to the fast convergence of the algorithm in the later stage. Finally,the local optimal model fitting was performed by using the GC-RANSAC algorithm to obtain the fine matching feature point set and achieve image registration and stitching with high precision. Compared with algorithms such as ASIFT+RANSAC,GMS,AKAZE+RANSAC,GMS+GC-RANSAC,the results show that the proposed algorithm improves the average matching accuracy by 30. 34% and reduces the average matching time by 0. 54 s.

In order to achieve complementary advantages and information sharing of heterogeneous workflow systems among enterprises, concerning the workflow showing heterogeneous distribution and other characteristics, an interface design of heterogeneous workflow processes interconnection based on Web service was proposed. For the interconnection of heterogeneous processes, the solution of heterogeneous workflow interconnection was described from call interface，call mode and call return respectively. Taking example of SynchroFlow workflow process described by XPDL and ODE (Open Dynamic Engine) workflow process described by BPEL, the process calls between the workflows was achieved.
