The Design And Realization Of Generating The Special Image Overlay Effects In Facial Video

With the expansion and homogenization of information,people hope to reflect the personalized features in the video for gaining recognition,satisfying their inner experience and conveying their feelings,such as applying image overlay effects on the face and maintaining their relative positions.But because of the complexity of video processing,the general video post processing software which needs professional knowledge and a lot of manual operation is hard and not suitable for ordinary home users.The existing applications mainly put some predefined beauty effects or dynamic effects into personal video.Users can choose one from the given effects and the effects is added on the face in the video with the preset position.Those applications usually do not support the users to add,to edit or to modify their own effects or deformation position.The effects are usually not following the light and shading changes.In this paper,we propose a generation method for adding special map effects on Facial Video,including face detection,facial feature localization,tracking,map distortion,brightness adjustment and original video superposition algorithm technology,and made the corresponding tool for verification.The tool allows users to import their own image or design patterns into facial videos(including recorded video files and real-time video camera input)to generate the image overlay effects.They can edit the position,deformation,transparency and other parameters of effects.By auto locating the facial features,image overlay effects could be maintained on the relative position according to the face and dynamically adjust the effects in order to adapt to the situation of the input video texture shading.In addition to allow users to export the generated facial effects video,they can also save their own created effect configuration and share to other users,which can quickly expand the number of effects and user participation.The work in this paper can be used for the generation of the face effects in personal video which can meet the needs of the personal video sharing application.
