摘要： A method for detecting solid components in ground glass nodules (GGNs) in medical images, includes: performing an intensity-based segmentation on a segmented GGN to identify a high intensity region; and performing a shape analysis to determine whether the high intensity region is a solid component or a vessel, wherein the shape analysis comprises: computing a compactness of the high intensity region; and determining whether the high intensity region is a solid component or a vessel by using an area, a maximum distance on a distance transform map and the compactness of the region; or determining whether the high intensity region is a solid component or a vessel by scaling and normalizing the region and computing a compactness for the scaled and normalized region.

摘要： The invention relates to a method and system for implementing a relay channel, and an edge node, in which a media location service system monitors the number of orders of all nodes in an IPTV system, and, when monitoring that the number of orders of the central node of the IPTV system is more than a predetermined first threshold, searches edge nodes with the number of orders less than a predetermined second threshold, and sends a relay channel establishing request message to one of the edge nodes; the edge node which receives the message sends an RTSP link establishing request message to the central node, reserves a media distribute unit (MDU) resource for the link, and notifies the central node of the IP address of the reserved MDU resource; and the edge node enables the MDU resource, sends a media stream requesting message to the central node, and stores data of the relay channel. The invention can better balance the load of each node in the network, thereby allocating and using the system resource more properly.
