Embodiment approach

[0073] One implementation for implementing the above example includes:

[0074] Step 1. According to the technical solution provided by the embodiment of the present invention, obtain the corresponding position coordinates of the person's image in the current frame on the display coordinate plane.

[0075] Step 2: Using animation generation technology, generate the foreground of the footprint centered on the position coordinates obtained in Step 1, and add it to the background pattern.

[0076] Step 3: Display the image (including the background pattern and the foreground pattern) generated in step 2 on the display device.

[0077] For another example, the background pattern can be selected as sea water, the foreground pattern type is small fish, and the positional relationship is the second type, that is, the display position of the foreground pattern and the position of the person on the display plane are mutually exclusive. An implementation scheme for realizing this exampl...

Abstract

The invention discloses a method for generating video special effects and a device thereof, which are used for solving the problem in the prior art of bad effect of video special effects which are generated through collected images. The method for generating the video special effects provided by the invention comprises the following steps: corresponding relation between coordinates of regions on the ground which are acquired by image acquisition equipment and coordinates of display regions of a display device is preseted; display coordinates of objects on the display regions are determined according to the corresponding relation and the coordinates of the regions on the ground of the objects; the video special effects are generated according to the display coordinates of the objects.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method and device for generating video special effects. Background technique [0002] In the existing video special effects technology, either the video special effects are directly completed in the image space, or the motion information obtained in the video image data is used to drive the virtual 3D model. [0003] The current video special effects are generally realized on the two-dimensional image plane. By locating and tracking the faces in the video, the special effects are directly completed on the two-dimensional image space. These special effects are essentially realized through the filtering of the two-dimensional image. , such as mosaic, face blur, face replacement and other special effects. These video effects are very simple. [0004] The video special effect generation method that uses the motion information obtained in the video image data to drive the...
