  • Patent number: 11627370
    Abstract: Provided is dynamically converting a video being displayed on a user device according to changes in a holding direction and a display direction of the user device. The user device may include a processor: generate a request message for requesting a predetermined video to a contents server and transmit the request message to the contents server through the communication circuit, receive the requested video from the contents server in response to the request message through the communication circuit, detect a target object from each image frame of the received video and define a region of interest based on the detected target object; determine whether error occurs in detecting the target object at each image frame and correct the region of interest when error occurs; defining a crop region based on the corrected region of interest; and converting the received video to a second video based on the crop region.

  • Patent number: 11151747
    Abstract: Provided is creating an augmented reality video using a set-top box. The set-top box may include a communication circuit and a processor. The communication circuit may be configured to receive a first video stream including a target object image in real time from a server and to receive a second video stream captured by a user device from the user device. The processor may be configured to: extract the target object image from each frame of the first video stream using WebGL, correct a color of a boundary line of the target object image between the target object and the background, and composite the extracted target object image into an each frame of the second video stream.

  • Patent number: 11128815
    Abstract: An object extraction device for extracting an object from a video includes a tracking unit that tracks at least one object included in the video; a crop area setting unit that sets an area to be cropped in any one frame of the video based on coordinate information of the tracked object; a crop area movement determination unit that determines whether or not to move the crop area based on a location relation between the coordinate information of the tracked object and the crop area; and an extraction unit that extracts, from the video, a partial video corresponding to the crop area that is moved or not according to a result of the determination.

  • Patent number: 10728562
    Abstract: Provided is an apparatus may be provided for transmitting a moving image including an alpha channel. The apparatus may include an object region extractor configured to extract an object region from the moving image, a color frame generator configured to generate a color frame corresponding to the extracted object region, an alpha channel frame generator configured to generate an alpha channel frame corresponding to the object region based on the alpha channel included in the moving image, a synthesizer configured to generate a synthesized frame by synthesizing the color frame and the alpha channel frame; an encoder configured to encode the synthesized frame; and a transmitter configured to transmit the encoded synthesized frame to a reproducing device.
