  • Publication number: 20150195510
    Abstract: A method of integrating binocular stereo video scenes with maintaining time consistency includes: propagating and extracting a contour of moving object of stereo video A; integrating and deformating of parallax between moving object and dynamic scene with time consistency; color blending of moving object and dynamic scene with time consistency where a method of median coordinate fusion is utilized. The method is simple and effective to utilize a small quantity of user interactions to successfully extract moving objects from stereo video which are same in time and as consistent as possible between left view and right view to develop multiple constraint conditions to guide the integration and deformation of parallax of moving object and dynamic scene and allow moving object to conform to the rules of perspective of dynamic scene. Moreover, the deformation result of moving object is smooth and consistent and can avoid effectively the occurrence of “dithering” phenomenon.

  • Patent number: 9036860
    Abstract: The invention discloses a method for editing propagation of video and image content based on local feature structure preservation, comprising: mapping all pixels in the input original image and/or video key frames to a selected feature space; finding K nearest neighbor pixels for each pixel according to feature vectors' Euclidean distance in the selected feature space; using Locally Linear Embedding (LLE) dimension reduction to construct the locally linear relationship between each pixel and its K nearest neighbor pixels in the selected feature space; According to the present invention, it is possible to accurately perform such image or video processing as automatic color transformation, interactive color editing, gray image colorization, video cloning and image matting.
