The present invention relates to a method for generating a user profile in indexing/browsing of multimedia data and a multimedia browsing method using the same. The multimedia data browsing method is characterized in that: (a) constructing a user profile by incorporating a user-preferred application description scheme indicating a user-preferred multimedia browsing method or browsing criterion, wherein the browsing method or browsing criterion is described in different way according to a type of the multimedia data in terms of genre; (b) analyzing the user-preferred application description scheme and selecting a relevant application for implementing a user-preferred browsing; and (c) browsing corresponding multimedia data using the selected preferred application.

The present invention discloses a method for extracting an object region in a motion picture, which can extract the object region of a current frame using different methods based on a degree of motion of the object. Especially, when the object has many motions, an object region of a previous frame is modified by comparing a CDI (Change Detected Image) generated based on a difference between the previous frame and the current frame with the previous frame. As a result, the present invention can be applied to image communication requiring real-time processing, and also applied to techniques requiring precise background change by dividing the object region in pixel units.

Disclosed is a face extraction method using color distortion information. The face extraction method includes extracting color distortion information from the given image, determining a skin color range in a color space using the extracted color distortion information, and performing the face extraction by extracting the skin color region using the determined skin color range. According to the method, the face is more accurately extracted by extracting the color distortion information of a still image or moving image when the image is given, and variably and automatically determining the skin color range suitable for the given image using the color distortion information.

A method of detecting a specific object in an image signal both efficiently and accurately is disclosed. According to the method, an object is first detected from an image or frame using a general feature of the object and in the following image or frame, the object is detected using an object-dependant feature. Also, when detecting a plurality of objects or portions of the object, a full color range of the specific object is determined, and color range sections of the full color range is used to detect the object.

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.
摘要:
The present invention relates to optically active quinoline carboxylic acid derivatives, their pharmaceutically acceptable salts, their solvates, and a process for the preparation thereof. More specifically, the present invention relates to optically active quinoline carboxylic acid derivatives containing 4-aminomethyl-4methyl-3-(Z)-alkoxyiminopyrrolidine substituents causing optical activity at the 7-position of the quinolone nuclei. As the compounds of the present invention have superior antibacterial activity and pharmacokinetic profiles to their enantiomers, their racemates and conventional antibacterial agents, with nearly no phototoxicity, the compounds of this invention are useful for antibacterial agents.

摘要:
A method of searching or browsing multimedia data which can effectively search or browse an image is disclosed. In the present method, the searching or browsing is performed in consideration of at least one of a reliability information on a weight of a feature of an input multimedia data and an authority code. According to the method, the system selects reference multimedia data, and searches the multimedia data using a weight of a feature and/or a feature element of the input multimedia data. A user gives feedback on the relevance of the searched or browsed multimedia data, and the system calculates a new weight using the relevance information. Thus, the system updates and maintains new weights of features and/or feature elements.
