Abstract

The invention belongs to the technical field of image processing, and discloses a fusion coefficient determination method and device, electronic equipment and a storage medium. The method comprises the following steps: determining a fusion region mask according to an original image and a fused image; segmenting the fusion region mask to determine a connected domain; and determining a fusion coefficient according to the mask of the connected domain, the original image and the fused image. According to the fusion coefficient determination method and device, the electronic equipment and the storage medium provided by the invention, reverse solution of the fusion coefficient alpha can be realized, so that the value of the fusion coefficient alpha is accurately determined.

Description

technical field [0001] The present application belongs to the technical field of image processing, and in particular relates to a method, device, electronic device and storage medium for determining a fusion coefficient. Background technique [0002] In addition to providing the main video of the content, the existing video playback interface often incorporates some controls, bullet screens, and subtitles of the App. Therefore, the video viewed by the user is essentially the result of a fusion of different layers including the main video. [0003] The currently commonly used image fusion method is the alpha fusion method, the formula of which is A×(1-alpha)+B×alpha=result; where alpha is the fusion coefficient, A is the original image pixel, and B is the fusion layer pixel. like figure 1 As shown, in order to generate the final displayed picture, the original video information (video), the fusion layer (layout) and the fusion coefficient alpha are indispensable.
