  • Patent number: 11488288
    Abstract: Disclosed are a method and an apparatus for processing a blurred image. The method for processing a blurred image includes the steps of generating a first input feature map and a second input feature map with a feature distribution for blur removal from the blurred image, generating a prediction feature map from the first input feature map by using a self-spatial feature transform (SSFT) module which transforms the feature distribution for blur removal into a feature distribution for face recognition without external information, and generating a deblurred image based on the second input feature map and the prediction feature map.

  • Patent number: 8971410
    Abstract: A method of processing frames obtained by multiple exposures may include categorizing, by at least one processor, a plurality of frames captured by multiple exposures into one of a reference frame and a target frame, compensating for global motion resulting from motion of a capturing apparatus capturing an object, and compensating for local motion resulting from motion of the object, based on a joint histogram between the reference frame and the target frame.

  • Patent number: 8942509
    Abstract: An apparatus and method creating a ghost-free High Dynamic Range Image (HDRI) based on filtering are provided. It is possible to effectively prevent a ghost phenomenon from occurring when a single HDRI is created from a plurality of LDRIs, by defining a ghost area using a probability based on a global transfer function indicating a relationship for intensities of several frames, rather than searching for or identifying a ghost area in a single or each image.

  • Patent number: 7291193
    Abstract: A cyclone dust collector and a vacuum cleaner having the same. The cyclone dust collector has a cyclone body shaped to have a relatively wider upper portion and a relatively narrower lower portion and also has a suction port and a discharge port, a grill member connected to the discharge port, a dust receptacle connected to the cyclone body, and a blocking member for partially blocking the grill member. Air drawn in through the suction port moves in an increasingly wider radial path as it travels upwardly to the discharge port, increasing the centrifugal force on suspended particles as they travel toward the discharge port. The shape of the cyclone body prevents turbulent flow from being generated. Dust is prevented by the blocking member from attaching to the grill member before being centrifuged, performance of the grill member is enhanced.
