Problems solved by technology

But it still consumes a lot of time for viewers, and fast-forward is a way of skipping and playing, fast-forwarding to view the video, there is still the possibility of missing important pictures
On the other hand, the time period in which the target object appears in the video may only be a dozen seconds or even a few seconds. In addition to the above-mentioned waste of a lot of time spent watching static images, there is still a lot of time wasted in the existing methods of manually finding the target. Identification and screening of non-target persons

Embodiment Construction

[0074] The method according to the present invention will be further explained below in conjunction with the drawings. In the form of examples, specific processes such as background modeling, front background separation, feature extraction and feature comparison are described in detail.

[0075] The search method of the present invention is a video analysis search method that combines multiple video analysis technologies, and its main analysis processing flow is as follows figure 1 Shown. The following describes the specific process of the method described in this example step by step, taking the searcher as an example.

[0076] First, the establishment and learning of character modules.

[0077] Section 1.1, the establishment of character modules: such as figure 2 As shown, in the sample, the outline of the character is manually selected, and each circle can be regarded as a coordinate (for example, two points from the top of the head, from left to right are point(215,70), point(2...

Abstract

The invention belongs to the technical field of video analysis and processing, and discloses a method for searching a target in a video. The method comprises the following steps of: on the basis of a foreground / background separation technology and a feature comparison technology, extracting the feature parameters of a target object; separating a foreground object from a video to be detected; extracting the feature parameters of the foreground object one by one; comparing the feature parameters with the features of the target object one by one; and inputting a searching result according to a comparison result. According to the method, the aim of searching a target in a video is fulfilled. On the aspect of application, the method contributes to the improvement of the conventional video monitoring system, and plays important and practical roles in saving human resources, time cost and the like; and on the aspect of technology, a portrait feature comparison technology is applied to target searching practice for the first time, and meanwhile, the conventional feature technology is improved, so that the accuracy of the feature comparison is further increased. Technology progresses in the fields of monitoring and investigation search are facilitated.

Description

Technical field [0001] The invention belongs to the technical field of video analysis and processing, and relates to the extraction and feature matching of moving objects, and specifically discloses a method for searching for a target object in a video. Background technique [0002] With the continuous development of digital camera technology, video surveillance as a security precaution is widely and widely used in daily and professional criminal investigation fields. While video surveillance has brought irreplaceable guarantees for security and other aspects, the existing video surveillance system is too simple, inconvenient for video viewing and target finding, and other shortcomings have gradually emerged. [0003] With the current common surveillance system, when you need to view the surveillance video and look for a target in the video, you must manually view the entire video completely. However, on the one hand, in the actual application process, in the camera monitoring are...
