This invention relates to a parallel and distributed man-face identifying method based on network, which applies an improved man-face identifying method based on line sections to allocate the computing and operation on the network, utilizes the strong computation and storage ability of the nodes in the network and their corporation to carry out parallel and distributed identification operation to increase the identifying speed of man-faces. The method includes the following steps: configuring network to set up an adjustable node computation tank, picking up man-face images in a video flow.
