| 20110026606 | SYSTEM AND METHOD FOR ENHANCING THE VISIBILITY OF AN OBJECT IN A DIGITAL PICTURE - The visibility of an object in a digital picture is enhanced by comparing an input video of the digital picture with stored information representative of the nature and characteristics of the object to develop object localization information that identifies and locates the object. The visibility of the object and the region in which the object is located is enhanced by image processing and the enhanced input video is encoded. | 2011-02-03 |
| 20110026607 | SYSTEM AND METHOD FOR ENHANCING THE VISIBILITY OF AN OBJECT IN A DIGITAL PICTURE - The visibility of an object in a digital picture is enhanced by comparing an input video of the digital picture with stored information representative of the nature and characteristics of the object to develop object localization information that identifies and locates the object. The input video and the object localization information are encoded and transmitted to a receiver where the input video and the object localization information are decoded and the decoded input video is enhanced by the decoded object localization information | 2011-02-03 |
| 20110026608 | METHOD OF ENCODING VIDEO CONTENT - In a method of encoding video content, bits of a first view and a second view of a three-dimensional (3D) video content are manipulated to occupy a first slice of video and a second slice of video, wherein a boundary is configured to be formed between the first and second slices. In addition, the bits of each of the first slice and the second slice are encoded separately from each other to form a first independently compressed video slice and a second independently compressed video slice. The first and second independently compressed video slices are then multiplexed to form at least one transport stream operable to be processed to render at least one of two-dimensional (2D) and 3D video. | 2011-02-03 |
| 20110026609 | IMAGE TRACKING AND SUBSTITUTION SYSTEM AND METHODOLOGY - The present invention relates to a system and method for processing a video input signal providing for tracking a selected portion in a predefined audiovisual presentation and integrating selected user images into the selected portion of the predefined audiovisual presentation. | 2011-02-03 |
| 20110026610 | ENCODER - A method and apparatus for encoding media content. In the field of video compression, temporal compression generates I-frames and dependent P-frames and B-frames. The placement of I-frames is determined by the presence of scene switches in the video. In order to improve the ability of a user to seek to interesting parts of the video, a video encoder considers semantic data identifying narrative points of interest within the video. The encoding process generates encoded video data having I-frames present at scene transitions and also at narratively interesting parts of the video. | 2011-02-03 |
| 20110026611 | IMAGE PROCESSING APPARATUS AND METHOD - Provided is an image processing apparatus including: area determination unit configured to determine whether or not an area of a control block functioning as control unit for filtering of an image includes a processing-target slice area of a plurality of slices formed in a frame of an encoded image; control information creation unit configured to create filter control information representing whether or not the filtering is performed for the area of the control block including a processing-target slice for each area of the control block including the processing-target slice when the area determination unit determines that the area of the control block includes the area of the processing-target slice; and filter unit configured to perform filtering for the image based on the filter control information created by the control information creation unit. | 2011-02-03 |
