Problems solved by technology

[0003] However, in the existing technology, the pixels of the middle frame number of the video image cannot be effectively selected, and the characteristics of the image itself cannot be well represented, which reduces the efficiency of image extraction. Accuracy, at the same time, for the extraction method of moving targets, the amount of calculation is too large to accurately extract moving targets

Embodiment Construction

[0039] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0040] see figure 1 As shown, the moving target analysis and recognition algorithm for multi-channel 4K quasi-real-time splicing video, the specific algorithm steps are as follows:

[0041] Step 1, constructing a background image;

[0042] S1: The image frame difference method is used to construct the background image, that is, the moving target is constantly moving in the current background, and the image sequence of the moving target is obtained. The image sequence is a series of images of the moving target that are sequ...

Abstract

The invention discloses a moving target analysis and recognition algorithm for multi-path 4K quasi-real-time spliced videos, relates to the technical field of moving target analysis and recognition, solves the technical problem that in the prior art, a moving target extraction method is large in calculation amount and cannot accurately extract a moving target. a background image is constructed a background image is constructed by adopting an image frame difference method, i.e., an image sequence of a moving target is obtained by continuously moving the moving target under the current background, and pixel points in a middle frame number are selected stably, so that the characteristics of the image can be better expressed, and the accuracy of image sequence selection is improved; according to the method for extracting the moving human body, the calculated amount is small, the human body target can be accurately extracted, the moving mode of the human body target can be dynamically displayed, the working efficiency is improved, and meanwhile the quality of an extracted image of the human body target is improved.

Description

technical field [0001] The invention relates to the technical field of moving target analysis and recognition, in particular to a moving target analysis and recognition algorithm for multiple 4K quasi-real-time spliced ​​videos. Background technique [0002] An image is obtained by observing the objective world in different forms and means with various observation systems, and can directly or indirectly act on the human eye and then produce an entity of visual perception. Vision is an important functional means for human beings to observe and perceive the world. Visual information comes from images, and the images here are in a relatively broad sense, such as photos, drawings, animations, videos, etc.; digital image processing refers to the use of digital computers to process and process images, and the knowledge involved in the subject of digital image processing Very broad, with a wide variety of specific approaches. Traditional image processing technologies mainly focus...
