20090219933SYSTEM, SERVER AND METHOD FOR OPTIMIZING A GROUP MANAGEMENT PROTOCOL - The present invention discloses a method, server and system for optimizing a group management protocol so as to reduce the complexity in setting and switching filter modes in the prior protocols. The method includes: a group member sends a membership report to a multicast router; upon reception of the membership report, the multicast router judges whether the report carries an EXCLUDE mode non-empty source list; if so, the router updates a corresponding state inside the router according to a non-source-specific join; or else, the router updates the corresponding state inside the router directly with the information of the report. The method provided by the present invention can avoid the complex switching and processing of filter modes in the prior protocols.09-03-2009
20090296709METHOD AND SYSTEM FOR SWITCHING MULTICAST TRAFFIC AND ROUTER - A method for switching multicast traffic includes: entering, by a second router, a waiting state after receiving a packet indicative of recovery of a first router; and deleting, by the second router, the egress interface of MFIB entries on the second router after receiving a data packet or an Assert packet from the first router. A router and a system for switching multicast traffic are also provided herein.12-03-2009

20080281203System and Method for Quasi-Real-Time Ventricular Measurements From M-Mode EchoCardiogram - A method for measuring ventricular dimensions from M-mode echocardiograms, includes providing a digitized M-mode echocardiogram image, running a plurality of local classifiers, where each local classifier trained to detect a landmark on either an end-diastole (ED) line or an end-systole (ES) line in the image, recording all possible landmarks detected by the classifiers, where a search range in an N-dimensional parameter space defined by the landmarks for each dimension is reduced to a union of subsets, where each dimension of the parameter space corresponds a landmark, for each combination of possible landmarks, checking if an order of the landmarks is consistent with a known ordering of the landmarks, and if the order is consistent, running a global detector on each consistent combination of landmarks to find a landmark combination with a highest detection probability as a confirmed landmark detection, where the landmarks are used for measuring ventricular dimensions.11-13-2008
20090010509Method and system for detection of deformable structures in medical images - A method and system for detection of deformable structures in medical images is disclosed. Deformable structures can represent blood flow patterns in images such as Doppler echocardiograms. A probabilistic, hierarchical, and discriminant framework is used to detect such deformable structures. This framework integrates evidence from different primitive levels via a progressive detector hierarchy, including a series of discriminant classifiers. A target deformable structure is parameterized by a multi-dimensional parameter, and primitives or partial parameterizations of the parameter are determined. An input image is received, and a series of primitives are sequentially detected using the progressive detector hierarchy, in which each detector or classifier detects a corresponding primitive. The final detector detects configuration candidates for the deformable structure.01-08-2009
