A method for a dominant color setting of a video region and a data structure and a method of a confidence measure extraction are disclosed. The video region dominant color setting method is characterized in that a region dominant color descriptor is expressed by the number of dominant colors with respect to a certain region, a dominant color expressed, a frequency that the dominant color appears, and an accuracy of a color value representing the region in a region dominant color based on various region dominant color extraction methods, for thereby expressing a region dominant color using a plurality of colors with respect to a region dominant color value and a confidence value of a region dominant color information based on various region dominant color feature extracting methods.

System, method, and multi-level object data structure thereof for browsing a multi-media data, the method for browsing a multimedia data using a multilevel object data structure including the steps of (1) receiving multimedia information and multiple supplementary information on each object in the multimedia information on the same time, (2) separating the multimedia information and the multiple supplementary information, (3) displaying the multimedia information, and (4) browsing/searching supplementary information related to a particular object from the multiple supplementary information, and displaying the supplementary information when a user requests for browsing/searching the supplementary information related to the particular object.

System, method, and multi-level object data structure thereof for browsing multimedia data

The present invention relates to an effect color extracting method of an image and an image original color recovering method which are capable of automatically extracting an effect color of an image pictured in accordance with an environment of a certain illumination and a color lens (or filter) and a feature of a camera, adjusting the extracted effect color and recovering an original image color of the image for thereby enhancing a performance of an image search. In the method for recovering an image color pictured based on a certain effect of an original color or other colors or an effect color in accordance with a feature of a camera and a surrounding environment of an object, an image color recovering method includes the steps of comparing all pixels of a frame of the image and a first critical value, obtaining an average hue value Hue_Ave with respect to the hues of the pixels each having a crominance smaller than the first critical value, computing a hue corresponding to the average hue value Hue_Ave, and determining the computed hue as an effect color, and compensating the image color affected by the effect color using the computed hue and adjusting the image color to an original color.

The present invention relates to a multimedia retrieval system and a method thereof which is capable of performing a multimedia data retrieval among different systems using color histograms constructed with different color spaces and color quantization methods, in particular to a content-based multimedia retrieval system and a method thereof which is capable of retrieving multimedia data among different systems, by extracting or converting a color histogram of a query image or a color histogram of an image to be retrieved into a color histogram of the same color space and color quantization method each other, and using the extracted or converted color histogram.

Content-based multimedia retrieval system and method thereof

A method for quantization of a color histogram bin value of an image or video, and more particularly, a method for non-uniform quantization of a color histogram bin value of an image (or video) according to the frequency of color occurrence is provided. The methods effectively represent the characteristics of a color histogram of an image in comparison to conventional art, and improve the performance of image retrieval when an image (video) retrieval search is conducted.

Method for quantization of histogram bin value of image

A method is provided for setting a dominant color using a spatial coherency in order to improve performance of an image search function. The method includes describing an image region based on several dominant colors, a frequency of each dominant color, and a spatial coherency (SC) of the dominant color. In the method, the spatial coherency is non-uniformly quantized based on a predetermined threshold. For example, the spatial coherency (SC) may be ranged from 0 to 1 and the threshold may be set to 0.70.

Method for setting dominant color using spatial coherency

A valve assembly of hermetic compressor is disclosed, in which a valve insertion groove () and () are formed. The valve insertion groove () includes a suction opening () on a head () provided between a cylinder () and a head cover (), and the valve insertion groove () includes a discharge opening (). An insertion type suction valve () and an insertion type discharge valve () are connected to said valve insertion grooves () and () respectively by spot welding. Accordingly, the valve assembly of hermetic compressor can make the valve smaller and simpler, so that reduced fabricating cost and improved productivity can be obtained. Also, at the same time dead volume can be reduced, thereby improving the compression efficiency.

A video-on-demand (VOD) system and method which efficiently enables a user to resume viewing of a video program from an interrupted position is disclosed. The present invention allows the user to resume viewing of a video program even if the user requests a resumption of the interrupted video program several times or through different video servers. Particularly, the video viewing characteristic information of a user terminal is not managed by a video server of the VOD system, but is managed by the user terminal. Accordingly, when a user interrupts viewing of a video program, the video server transmits to the user terminal user profile information which includes the characteristic information related to the viewing of the video program. Thereafter, if the user requests resumption of the interrupted video program using the user profile information, the video server re-transmits the video program from the interrupted position of the video program.

Video-on-demand system and video viewing assisting method

A crankshaft in a dual capacity compressor is disclosed, which causes oil contained in a lower portion of the compressor to flow up to an upper portion thereof with respect to all the rotational directions of a motor. A crank shaft () includes a driving shaft () inserted into a reversible motor () for rotating along with the motor (), a balance weight () formed in a top portion of the driving shaft () for preventing vibration during rotation from occurring, a crank pin () formed on an upper surface of the balance weight () to be eccentric from the center of the driving shaft (), and a regular/reverse oil path () formed along the balance weight () and the crank pin () for moving oil for forward rotation and reverse rotation of the motor respectively. The crankshaft serves to stably lubricate each driving part of the dual capacity compressor regardless of rotation direction.
