A method and apparatus for correcting an error in depth information estimated from a two-dimensional (2D) image are disclosed. The method includes diagnosing an error in depth information by inputting a color image and depth information estimated using the color image to a depth error detection network, and determining enhanced depth information by maintaining or correcting the depth information based on the diagnosed error.

Method and apparatus for correcting error in depth information estimated from 2D image

A method and apparatus for an adaptive Hypertext Transfer Protocol (HTTP) streaming service using metadata of content are provided. The metadata of the content may be efficiently divided for a purpose of use of a terminal based on general media information or specific media information, and may be transmitted to the terminal. A group may include one or more representations of content. The metadata may include a group element, and the group element may provide a summary of attributes of one or more representations included in the group.

Method and device for providing streaming content

The present invention provides a method for image preprocessing, the method including: identifying a plurality of input images to process image registration; selecting at least one transformation method among histogram equalization and gamma transformation in consideration of hue and brightness values of the plurality of input images; processing the histogram equalization on the plurality of input images in response to the histogram equalization method being selected; and processing the gamma transformation on the plurality of input images, in response to the gamma transformation method being selected.

Method and apparatus for image preprocessing

The present invention relates to an apparatus and a method of stitching a real-time image. More specifically, stitching-related information is generated, a parallax occurrence region in an overlap region is tracked, and correction for reducing parallax occurring in the parallax occurrence region and correction of an image distortion occurring in a non-overlap region are performed for output.

Apparatus and method of parallax-minimized stitching by using HLBP descriptor information

Disclosed is an apparatus and method of generating a stitched image. A method of generating a stitched image according to the present disclosure includes: obtaining a plurality of input images; determining whether or not a parallax problem occurs between overlapping areas of the obtained input images; updating a predetermined look-up table according to the determination; and generating a stitched image by applying the updated look-up table to the input images.

Apparatus and method of generating stitched image based on look-up table

A method and apparatus for an adaptive Hypertext Transfer Protocol (HTTP) streaming service using metadata of content are provided. The metadata may include a minBufferTime attribute indicating a minimum amount of initially buffered media content. A terminal may receive content from a server before playback of the content, and may buffer the content by at least the minimum amount. The metadata may include a range attribute that designates a range of a target indicated by a Uniform Resource Locator (URL). The terminal may receive bytes designated by the range attribute from the URL, and may play back the content using the received bytes.

Apparatus and method for providing streaming content

Disclosed is a method and apparatus for encoding/decoding an image. The image encoding apparatus according to an embodiment of the present disclosure may include: an encoding level decision unit determining an encoding level of an input image; a sampling unit outputting an encoding target picture associated with the encoding level determined in the encoding level decision unit; an encoding unit encoding the encoding target picture output from the sampling unit; a reference picture storage unit storing at least one reference picture; and a reconstructed image generation unit generating a reconstructed image corresponding to the input image in association with the encoding level determined in the encoding level decision unit.

Method and apparatus for image encoding and decoding

Apparatus and method for providing streaming contents

A method and apparatus for an adaptive Hypertext Transfer Protocol (HTTP) streaming service using metadata of content are provided. The metadata may include one or more BaseURL elements. Uniform Resource Locators (URLs) of segments forming media may be generated based on the BaseURL elements. Additionally, a URL of a segment may be generated by mapping a BaseURL element among the BaseURL elements to a sourceURL attribute of the segment. Segments indicated by generated URLs may be identical to each other.

A method and apparatus for an adaptive Hypertext Transfer Protocol (HTTP) streaming service using metadata of media content are provided. The media content may include a sequence of one or more periods. The metadata may include a start time attribute and/or a duration attribute of each of the periods. The metadata may determine a start time of each of the periods, and a start time of each of segments included in each of the periods. A terminal may access segments included in each of the periods, may decode and render data of media content included in the segments, and may play back the media content.
