[0057] Next, we will refer to image 3 An apparatus 200 for recognizing objects in a video according to another embodiment of the present invention is described. Such as image 3 As shown, the device 200 for recognizing objects in a video includes object feature extraction means 101 , text information processing means 102 , online image search means 103 , matcher 104 and retrieval means 201 . Among them, referred to figure 1 The object feature extracting means 101, the text information processing means 102, the online image searching means 103, and the matcher 104 are described in detail, and thus descriptions thereof will be omitted.

[0058] The retrieval means 201 is configured to extract video segments related to the candidate object determined by the matcher 104 or to the filtered text from the video.

[0059] As mentioned above, the matcher 104 determines the candidate object or the filtered text or both, that is, the matcher 104 determines the corresponding relations...

Abstract

The invention discloses equipment and a method for recognizing objects in video. The equipment comprises an object feature extracting device, a text information processing device, an online image searching device and a matcher. The object feature extracting device is configured in such a manner that candidate objects can be extracted from the video and features of the candidate objects can be extracted; the text information processing device is configured in such a manner that text information contained in the video can be extracted and can be filtered by the aid of a keyword database to obtain filter texts relevant to the candidate objects; the online image searching device is configured in such a manner that images corresponding to the filter texts can be searched in an online manner and features of the images can be extracted; the matcher is configured in such a manner that the features of the candidate objects and the features of the images can be matched with one another, the candidate objects or the filter texts can be determined on the basis of matching results or the candidate objects and the filter texts can be simultaneously determined on the basis of the matching results.

Description

technical field [0001] The present invention relates to the fields of pattern recognition and image retrieval, and more particularly, to a device and method for recognizing objects in a video. Background technique [0002] Recognizing objects in videos such as human faces and then performing character retrieval can provide viewers with functions such as fast character positioning, key scene positioning, and story summaries in long-form film and television works. With the prosperity of video media in the Internet age, the audience's demand for character retrieval is increasing day by day. They hope to browse some short clips of the play before watching a complete film and television play, and then make further choices. [0003] An important video retrieval technology capable of realizing the above functions is the automatic retrieval of role tables, wherein the role tables specifically refer to lists of main characters in film and television dramas such as feature films, TV d...
