Abstract

The invention relates to a method for acquiring a sequence image motion target area in real-time. The method comprises the following steps: executing frame difference processing on an acquired static image sequence to obtain a frame difference image sequence; dividing each of frames of the frame difference image sequence into W*H sub-areas, and calculating a energy logarithm value for each of the sub-areas; acquiring a feature value for each of the sub-areas according to the energy logarithm value for each of the sub-areas; determining whether each of the sub-areas belongs to the motion target area; and obtaining the whole motion target area. The method for acquiring a sequence image motion target area in real-time can be suitable for the situations such as a complex background, a natural environment and the like.

Description

technical field [0001] The invention relates to the technical field of image processing and target monitoring, in particular to a method for acquiring a moving target area of ​​a real-time sequence image. Background technique [0002] At present, the key technology of the target monitoring system includes the key moving target area extraction. Whether the system can accurately acquire moving target areas in complex backgrounds and natural environments (the number of targets N≥1, and targets can include single moving targets, multiple moving targets, mixed moving targets, etc.) directly affects the system backend and users’ perception of Target alarm and follow-up processing, especially in the field of real-time monitoring and intelligent security, has great application requirements for real-time moving target area acquisition, so it has become one of the key technologies in the research of image processing and monitoring security. [0003] When acquiring the moving target a...
