Embodiment Construction

[0047] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0048] The method for determining and identifying images in the embodiments of the present application can be applied to image archiving. For example, when archiving video streams collected by monitoring equipment, the method for determining and identifying images in the embodiments of the present application can be used to determine the presence of the same face in the video stream. Each frame of the face frame in the image to be recogn...

Abstract

The embodiment of the invention provides a method and device for determining an identification image, and relates to the technical field of video processing, and the method comprises the steps: obtaining the image quality of a to-be-pushed frame image and the number of current pushed frame images; Wherein the to-be-pushed frame image and the pushed frame image are images which are obtained from ato-be-processed video shot by monitoring equipment and aim at the same to-be-identified object; Wherein the pushed frame image is an image which is located in front of the to-be-pushed frame image according to shooting time and meets a frame pushing strategy; And if the image quality of the to-be-pushed frame image, the number of the pushed frame images and the maximum frame pushing number meet the frame pushing strategy, outputting the to-be-pushed frame image, and updating the number of the pushed frame images. And a frame pushing strategy is dynamically adjusted according to the image quality of the to-be-pushed frame image, the number of pushed frame images and the maximum frame pushing number, and ensuring the balance of the quality, the time delay and the calculated amount of the pushed frame image.

Description

technical field [0001] The present invention relates to the technical field of video processing, in particular to a method and device for determining a recognized image. Background technique [0002] In today's society, due to the needs of security management, monitoring equipment is full of streets, communities, buildings and other public places. When a police situation occurs, first determine the image of the suspect or the suspect vehicle from the video data collected by the monitoring equipment, and then the police officers search for the suspect or the suspect vehicle based on the image of the suspect or the suspect vehicle. [0003] In the prior art, after the monitoring equipment collects the video stream, it usually detects and recognizes each frame of image in the video stream, determines the face or vehicle and other objects in each frame of image, and then detects the detected objects in each frame of image Objects are matched to determine all images of an object...
