Embodiment Construction

[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] In the embodiment of the present invention, the face image similarity first means that the face image similarity is the largest. An embodiment of the present invention provides a video image clustering method, comprising: acquiring multiple video images in video frames; comparing the similarities of the video images in the acquired multiple video frames, and calculating the The video images less than or equal to the first threshold are divided into different video image sub-clusters; from the video image sub-clusters, the second similarity value with the first video image is less than or equal to the second threshold. A video image is used as a typical video sample to form a typical sample set; a video index is generated according to the video image sub-clu...

Abstract

The invention discloses a video image clustering method which includes that a plurality of video images in the video frames are acquired; the similarities of the acquired video images in the video frames are compared; the video image with the first similarity value less than or equal to the first threshold is divided into different video image sub-clusters; the video image with the second similarity value of the first video image less than or equal to the second threshold is used as the video image typical sample, so as to generate the video image typical sample set. The invention embodiment is implemented to realize the rapid indexing of the video images in the monitoring videos.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a video image clustering method and system. Background technique [0002] With the development of society and the advancement of science and technology, the people's demand for safety is also getting higher and higher. Especially in the past two decades, security threats have occurred frequently: the 911 incident in the United States in 2001, the Russian terrorist bombing and hijacking in 2004, the Spanish railway bombing in 2004, and the British serial bombing in 2005. The occurrence of these incidents has made the governments of various countries attach great importance to cross-regional and cross-country social security prevention and anti-terrorism work. For our country, although no large-scale social security incidents have occurred, it is also facing the threat of terrorist activities. And with the increase of social mobility, the potential possibility of...
