摘要:
An apparatus for and a method of detecting a gradual shot transition in a moving picture The method includes: setting at least one feature point of a frame included in the moving picture, tracking the set at least one feature point, and setting a feature point of a subsequent frame, from the tracked at least one feature point; calculating a feature value corresponding to each feature point of each of the frames; and comparing corresponding feature values of corresponding feature points which are tracked for each of the frames, and determining that a gradual shot transition between the frames occurs when the comparison value is greater than a predetermined threshold value.

A method, medium, and apparatus detecting a real time event in a sports video. The method may include testing a confidence of an online model, calculated in a sports video stream, detecting an event by using an offline model in the sports video stream, when the confidence of the online model does not meet a threshold, training the online model through an event detected by using the offline model, and detecting an event by using the online model in the sports video stream, when the confidence of the online model meets the threshold.

A method, medium, and system generating navigation information of a sports video. The method may include detecting a candidate navigation point by analyzing video data in the sports video, and analyzing a caption from the candidate navigation point and generating the navigation information by determining a navigation section according to a result of the caption analysis.
摘要:
A video data processing system including a clustering unit to generate a plurality of clusters by grouping a plurality of shots forming video data, the grouping being based on a similarity between the plurality of shots, and a final cluster determiner to identify a cluster having the greatest number of shots from the plurality of clusters to be a first cluster and determining a final cluster by comparing other clusters with the first cluster.
摘要:
A method, medium, and system generating a video abstract with high processing speeds, may include a detecting of an event candidate section from video data, based on audio information, a detecting of shot change information from the detected event candidate section, a detecting of final event sections from the detected event candidate section, based on the detected shot change information and visual information, and a generating of video abstract information by merging the extracted final event sections.

A method, medium, and system extracting text, including filtering a text domain image using a stroke filter, determining a color polarity of the text by using a response value of the stroke filter, binarizing the response value of the stroke filter, and expanding a local domain by using a binary domain generated by the binarization.
摘要:
Provided is an image interpolation method and apparatus using a reference block depending on a direction. The image interpolation method may generate a horizontal reference block and a vertical reference block each with respect to an inputted image, and determine interpolation directivity with respect to the inputted image using the generated horizontal reference block and vertical reference block, thereby performing an interpolation on an image based on accurate interpolation directivity. In particular, the image interpolation method may determine whether to verify interpolation directivity depending on an edge intensity of an inputted image, thereby performing a color filter array (CFA) interpolation on an image based on an edge direction without determining the interpolation directivity, when the edge intensity is strong.
摘要:
An image enhancement apparatus and method based on luminance information of a pixel. The image enhancement apparatus may determine luminance data of each of a plurality of pixels, and may adaptively determine a conversion ratio according to the luminance data to apply the conversion ratio to an input image, thereby performing image-enhancing. The image enhancement apparatus may adaptively converse the input image according to luminance data, thereby precisely and effectively performing image-enhancing.
摘要:
Apparatus and method for correcting a tone of a panoramic image. An image processing apparatus may acquire, from an overlapping region of a left image and a right image, ghost information based on an optimal threshold and a cost map in which a similarity between the left image and the right image is reflected, may generate a tone correction map based on a global tone correction function generated using the ghost information in the overlapping region, and based on a local tone correction level generated using local information of an optimal seam, and may correct the left image and the right image using a final tone correction map generated by applying, to the tone correction map, a weighting based on the left image and a weighting based on the right image.
摘要:
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.
