摘要:
A system and method for analyzing the motions of an object based on the silhouettes of the object are provided. The system includes a foreground detector, a contour extractor, a model generator, a corner histogram generator, and a value of similarity measuring unit. The foreground detector detects a moving foreground object from an input image. The contour extractor extracts silhouette contour of the detected foreground object, and the model generator generates mean value histogram models as references to determine motions of the object. The corner histogram generator generates corner histograms of hierarchical multiband in the extracted contour signal, and the value of similarity measuring unit calculates a value of similarity between the generated corner histogram of a current frame and the average model histogram in a histogram unit, measures a value making a value of similarity with the calculated current frame histogram maximum, and determines the measured value as a posture of the object in the current frame.

A method of extracting a foreground object image from a video sequence includes producing a reference background image by separating a background image from a frame image of the video sequence; producing edge information of the frame image and the reference background image; producing an edge difference image using the edge information; and extracting the foreground object image using the edge difference image based on the edge information.

Disclosed are an apparatus and a method for sensing photoplethysmogram and fall. According to the present invention, the apparatus and for sensing photoplethysmogram and fall may include: a sensor unit that senses acceleration and photoplethysmogram; a photoplethysmogram/fall determining module that synthetically tests sensed acceleration signals and photoplethysmogram signals sensed by the sensor unit to determine whether emergency occurs due to fall or emergency occurs due to photoplethysmogram; and a communication module that transmits the test results.

Provided are a thimble-type intermediation device and a method for recognizing a finger gesture using the same. The thimble-type intermediation device includes: a motion sensing unit sensing a motion of a user's finger and generating the sensed result as motion data; a tactile sensing block sensing a tactile behavior of the user's finger and generating the sensed result as tactile data; a control unit recognizing the gesture and tactile behavior of the user's finger on the basis of the generated motion data and tactile data, and outputting the recognition result as recognition result information; and a wireless communication unit transmitting the recognition result information to a robot system.

Disclosed is a typewriter system and a text input method capable of accurately recognizing words by correcting words input using a mediated interface device based on a dictionary. A plurality of texts are combined by referencing a text recognition order set in which recognition results of texts are arranged according to a recognition order from texts input through the mediated interface device and the combined text is filtered using part index maps formed of part words that are an accumulated set of texts forming complete words. The part words passing through the part index maps is again filtered using a dictionary including context information formed of a set of words in a specific category, thereby making it possible to accurately recognize the words. The part words that cannot form words in a dictionary are removed in advance using the part index maps, thereby improving the recognition efficiency.

摘要:
A system and method for aborting web services automatically. An application program container has a first web service application program embedded, intercepts a message that is transmitted and received between a second web service program located externally and the first web service application program, identifies the kind of an operation requested by the second web service application program, and keeps information required for compensation. A protocol manager generates and manages a first sub-transaction object by a request of the second web service application program. A local compensator compensates the first sub-transaction if a global transaction coordinator sends a command to compensate a second sub-transaction already committed. A protocol service unit transmits and receives messages for managing the first sub-transaction. A registration service unit registers the generated first sub-transaction with the global transaction coordinator.
