Embodiment Construction

[0060] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0061] figure 2 The flow chart of the method for the regional special effect transition provided by the embodiment of the present invention, such as figure 2 As shown, the specific steps are as follows:

[0062] Step 201: Determine that special effects are to be added to the image S, and calculate front and rear special effect scaling coefficients according to the special effect area and the default front and rear special effect images and masks.

[0063] The zoom factor of the front field effect is the zoom factor of the front field effect image when adding the front field effect image to the special effect area.

[0064] Correspondingly, the scaling factor of the rear special effect is the scaling coefficient of the special effect image of the rear field when the special effect image of the rear field is added to the special eff...

Abstract

The invention discloses a regional special effect transition method and a device. The method comprises the following steps: based on preset transition effect, transition duration, as well as front and back field special effects, calculating each transition image and transition mask; taking out a frame of transition image in turn, and matching the front or back field special effect areas in the frame of transition image with the special effect areas of the image which needs to be added with special effects, according to the preset transition effect; after the matching is completed, determining the location of the front or back field special effect areas of the image which needs to be added with special effects, according to the corresponding transition masks of the frame of transition image; then based on the determined location of the front or back field special effect areas, adding the front or back field special effects in the frame of transition image to the image which needs to be added with special effects. The invention can provide transition effects in the special effect adding process of special areas so as to enhance the user experience and achieve better illusive effect.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method and a device for transitioning regions with special effects. Background technique [0002] The so-called specific area special effect refers to adding a masked image or animation to a specific area of ​​an image, for example: adding a photo frame to a specific area of ​​an image, and adding a mask to a specific area of ​​an image such as a human face. [0003] Currently, when adding special effects to an image, a specific area in the image is directly replaced with a special effect image. For example: to figure 1 Add mask effects to the face in the left image of , then set the figure 1 The face in the left picture is directly replaced with a mask to get figure 1 on the right, the figure 1 The right image of is shown to the user. This will make the user feel abrupt and reduce the user experience. Contents of the invention [0004] The invention provides a...
