Embodiment Construction

[0029] 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.

[0030] Before explaining the embodiment of the present invention in detail, the system architecture involved in the method for extracting emoticons provided by the embodiment of the present invention is briefly introduced.

[0031] see figure 1 , in the embodiment of the present invention, the operator's terminal 101 initiates an emoticon extraction request for a target video clip to the emoticon extraction system 102, for example, extracting an emoticon in a movie.

[0032] The expression extraction module 1021 in the emoticon package extracting system 102 obtains the identification information (ID) of the target video segment carried in the expression package extraction request after receiving the expression package extraction reques...

Abstract

The invention discloses an emoticon package extraction method and a device, and belongs to the technical field of multimedia. The method comprises steps of after receiving an emoticon package extraction request for a target video segment, carrying out face detection on the target video segment; carrying out face feature extraction on each obtained target image including a face so as to obtain at least one piece of target face feature information; for each target face feature information, inputting the target face feature information into a pre-trained classifier; acquiring the probability of belong to different emoticon classifications of target images corresponding to the target feature face information output by the classifier; and if a designated emoticon classification whose probability is larger than a first preset threshold value exists in different emoticon classifications, using the target image as an emoticon package and extracting the emoticon package from the target video segment and marking the target image to be the designated emoticon classification. According to the invention, the emoticon package can be extracted in the video segment in a completely automatic manner without manual interception, so massive manpower and time are saved and the method and device are quite simple to operate.

Description

technical field [0001] The invention relates to the field of multimedia technologies, in particular to a method and device for extracting emoticons. Background technique [0002] In the era of mobile Internet, relying on the continuous development of social networking and the Internet, the way of communication between people has also undergone corresponding changes, from the earliest text communication to the gradual use of some simple symbols and emoticons, and then gradually evolved into an increasingly diversified Emoji culture. In other words, emoticons are a kind of popular culture formed after social software became active. It mainly consists of people using popular stars, quotations, animations, video screenshots, etc. as materials, and adding a series of matching text. used to express certain emotions. [0003] In the related art, the emoticon packs are usually extracted only for static pictures one by one, that is, the emoticon packs are manually obtained from the...
