Embodiments of the present invention disclose an information transmission control method, apparatus, and system. Implementation of the method includes: receiving, by a first communications server, information data from a first terminal served by the first communications server; determining, by the first communications server, a target identifier of the information data; and sending the information data to a second communications server if the target identifier belongs to identifier information of the second communications server, so that the second communications server sends the information data to a second terminal corresponding to the target identifier. The first communications server and the second communications server correspond to two communications platforms; and the first communications server determines a target of the information data from a local platform, and then performs cross-platform forwarding, thereby implementing cross-platform instant messaging.

The present invention discloses a method of volume-panorama imaging processing, which generates a volume-panorama image by subsequently splicing respective image frames from an image sequence obtained in a real-time way or stored in a medium based upon the fact that the immediately adjacent image frames have the largest correlation. The method comprises the steps of: reading the image sequence, and firstly initializing an aligned image and a spliced image; dividing the i-th image frame Finto a plurality of sub-regions; calculating a motion vector of the i-t image frame with respect to the aligned image; fitting the motion vector to calculate a transform coefficient; splicing the Fto the current spliced image based upon the transform coefficient, and updating the aligned image; entering into a self-adaptive selection of a next image frame until the end of the splicing; and outputting the current spliced image as a resultant image. Additionally, when the image Fis spliced, double-filtering architecture of selecting characteristic points through a filtering and selecting the valid motion vector of the selected characteristic points through the other filtering to reduce an alignment error may be adopted. According to the present invention, the volume-panorama imaging can be done quickly and accurately so that the reliability of images particularly meets a very high requirement of the ultrasonic iatric diagnose.
