Embodiment 1

[0024] A video image filter processing method provided by an embodiment of the present invention is introduced in detail.

[0025] refer to figure 1 , which shows a flow chart of a video image filter processing method in an embodiment of the present invention, which is applied to a mobile terminal, and the method includes:

[0026] Step 101, during video shooting, identify in real time the scene to which each frame of video image in the video belongs.

[0027] In this embodiment, in video shooting, there are many technical means for real-time recognition of the scene. Specifically, the extraction of image structure and texture features can be used to identify the scene, and the global feature information can also be used to identify the scene. The present invention is for identifying the scene. The technical means are not limited in detail, and appropriate technical solutions can be adopted according to the actual situation.

[0028] The video recorded by the mobile terminal...

Embodiment 2

[0037] refer to figure 2 , shows a flow chart of a video image filter processing method in another embodiment of the present invention.

[0038] Step 201, during video shooting, identify in real time the scene to which each frame of video image in the video belongs.

[0039] In this embodiment, to identify the scene to which each frame of video image belongs, if the video is longer, it may cause a large amount of calculation for the mobile terminal, and there are multiple frames per second in the video, and the shooting speed of the photographer does not make the The scenes in the picture show jumping switching, so the method of identifying the scene by setting the number of frames at intervals can be adopted according to the actual situation.

[0040] Step 202, establishing an association relationship between scenes and filter styles.

[0041] In this embodiment, the filter style corresponding to the identified scene is selected according to the corresponding relationship ...

Embodiment 3

[0063] A video image filter processing device provided by an embodiment of the present invention is introduced in detail.

[0064] refer to image 3 , showing a block diagram of a video image filter processing device in an embodiment of the present invention, deployed in a mobile terminal, characterized in that the mobile terminal includes a scene recognition module 301, a filter selection module 302, an image processing module 303:

[0065] The scene identification module 301 is used to identify the scene to which each frame video image belongs in the video;

[0066] A filter selection module 302, configured to select a filter style corresponding to the identified scene;

[0067] The image processing module 303 is configured to perform filter processing using a corresponding selected filter style for each frame of video image.

[0068] exist image 3 On the basis of the filter selection module 302, the device also includes an association relationship establishment module ...

Abstract

The invention provides a filter processing method and a device for a video image. The method comprises the following steps of during the video shooting process, recognizing a scene for each frame of a video image in a video in real time; selecting a filter style corresponding to each recognized scene; and subjecting each frame of the video image to the filter processing operation by adopting the selected filter style correspondingly. Through the processing operation of the video image, the frames of the video are not processed by adopting a unified filter style. Instead, the frames of the video are processed through automatically changing filter styles according to recognized scenes. Therefore, the requirement of a user on specially processing some images of the video can be met.

Description

technical field [0001] The present invention relates to the field of video, in particular to a method and device for filter processing of video images. Background technique [0002] With the development of science and technology, mobile terminals generally have the function of taking pictures and video recordings, and front and rear camera devices have long been standard configurations. People edit and process the captured video images to make the picture more exquisite and better express the information that users expect to convey. [0003] At present, the editing methods for video images generally use a filter style set in advance for shooting, or select a filter style for editing according to the video image after shooting. However, both of the above two editing and processing methods are to process the captured video images in a unified style. When a section of the video image needs special processing, such as processing a section of video image into a black and white h...
