  • Publication number: 20170011494
    Abstract: A video deblurring method based on a layered blur model includes estimating a latent image, an object motion and a mask for each layer in each frame using images consisting of a combination of layers during an exposure time of a camera when receiving a blurred video frame, applying the estimated latent image, object motion and mask for each layer in each frame to the layered blur model to generate a blurry frame, comparing the generated blurry frame and the received blurred video frame, and outputting a final latent image based on the estimated object motion and mask for each layer in each frame, when the generated blurry frame and the received blurred video frame match. Accordingly, by modeling a blurred image as an overlap of images consisting of a combination of foreground and background during exposure, more accurate deblurring results at object boundaries can be obtained.

  • Patent number: 9519998
    Abstract: The present disclosure relates to a three-dimensional montage generation system and method based on a two-dimensional single image. An embodiment of the present disclosure may generate a three-dimensional montage in an easy, fast and accurate way by using a two-dimensional front face image data, and estimate face portions, which cannot be restored by using a single photograph, in a statistic way by using a previously prepared face database. Accordingly, an embodiment of the present disclosure may generate a three-dimensional personal model from a single two-dimensional front face photograph, and depth information such as nose height, lip protrusion and eye contour may be effectively estimated by means of statistical distribution and correlation of data.
