In a surveillance system, a server and a plurality of cameras provided in a surveillance area are communicably connected to each other. The server includes a table memory that retains information on free resources of each of cameras. The server determines for each camera, a process to be executed by the camera, based on the information on the free resources of the camera, and transmits an instruction to execute the determined process to each camera. Each of the cameras executes a process corresponding to the instruction to execute, based on an instruction to execute the process transmitted from the server.

Surveillance system and surveillance method

A system for analyzing an echo image containing a contour of an organ with reduced manual operation is provided. The echo image is first obtained. A user manually sets, say, four points as known or initial points such that two of the known points provide a width of the contour and the other two of the known points provide a height of the contour. A search region including a connecting line segment connecting each pair of adjacent ones of the known points is set on the contour. A search line segment that originates from a point bisecting the connecting line segment of the search region and reaches an end of the search region is set. Each search line segment is sought for a contour point constituting the contour. A contour is formed by connecting the contour points on the search line segments. Three points may be set as the initial points such that two of the initial points provide a width of the contour and the other one is on top of the contour.
