Embodiment Construction

[0076] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0077] Before explaining and describing the embodiments of the present invention in detail, the application scenarios involved in the embodiments of the present invention will be described.

[0078] The object detection method provided by the embodiment of the present invention can be applied to an object detection scene, and specifically can be applied to a scene of detecting a preset object in a video.

[0079] For example, the video is a video of a sports game, and the preset object is a trademark of a sports brand. At this point, after the sports game video is obtained, the trademark in the sports game video can be detected, and subsequent advertisers can know the degree of visibility of their trademark in the sports game video acc...

Abstract

The invention discloses an object detection method and device, belonging to the technical field of computers. The method includes: determining the first video frame in the video frame without object detection in the video as a test frame; determining a plurality of candidate images in the test frame according to the image characteristics of the test frame, and determining Category and confidence of each candidate image; for at least one candidate image belonging to the same category among the plurality of candidate images, according to the highest confidence in the confidence of the at least one candidate image, the at least one candidate image The confidence is adjusted; according to the adjusted confidence of the plurality of candidate images, a plurality of target images containing preset objects are acquired from the plurality of candidate images. The present invention improves the accuracy when acquiring the target image from the test frame, avoids omission of relatively blurred target images in the test frame, and further improves the overall object detection effect of the video.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to an object detection method and device. Background technique [0002] With the rapid development of information media such as television and the Internet, massive videos are flooding people's lives. Certain objects in videos tend to carry a large amount of semantic information, so it is often necessary to perform object detection on videos to identify these objects from videos. For example, if a certain video is a sports game video, the object to be detected can be the trademark of a sports brand. Through the detection of the trademark in the sports game video, the advertiser can know the availability of its trademark in the sports game video. Depending on the degree. [0003] At present, when performing object detection on a video, for each video frame of the video, according to the image characteristics of the video frame, it can be determined that multiple candidate images ...
