Provided is a method of providing a recognition result of an object, the method including: detecting an object included in an image; determining an image group corresponding to the detected object through matching between the image and image groups each grouped for a same object; and outputting information of the image group in a front direction of the object of the determined image group, estimated from the image, based on a photographing condition of the determined image group and a photographing condition of the image.

A method of displaying electrocardiograms comprises displaying a reference electrocardiogram; and displaying a measured electrocardiogram so that the reference electrocardiogram and the measured electrocardiogram are displayed in an overlapping state.

Method and user interface device for displaying electrocardiograms

A method is provided. The method includes in response to a new query or new input data being input, calculating a required minimum number of cycles per unit time which corresponds to the minimum number of cycles per unit time that is required to process the new query or the new input data, selecting a query to execute first, calculating the number of cycles to be processed during the time period set in advance by multiplying the calculated, required minimum number of cycles per unit time with a time period that is allocated to process the selected query or the input data and is set in advance, and putting a system into a dormant state for a remaining period of time in response to the calculated number of cycles being completely executed within the time period set in advance.

Provided are a method and apparatus for controlling load shedding for excluding data streams input into a data stream management system (DSMS). A method of selecting data not to be in the data process may be determined. A load shedding factor may also be determined. Data streams of the data process may be processed by applying the method of selecting the data according to the load shedding factor.

Method and apparatus for controlling load shedding in data stream management system

The apparatuses and methods described herein may operate to identify, from an index structure stored in memory, a reference minimum bounding shape that encloses at least one minimum bounding shape. Each of the at least one minimum bounding shape may correspond to a data object associated with a leaf node of the index structure. Coordinates of a point of the at least one minimum bounding shape may be associated with a set of first values to produce a relative representation of the at least one minimum bounding shape. The set of first values may be calculated relative to coordinates of a reference point of the reference minimum bounding shape such that each of the set of first values comprises a first number of significant bits fewer than a second number of significant bits representing a second value associated with a corresponding one of absolute coordinates of the point.

Compression scheme for improving cache behavior in database systems

A scheme for accessing a multi-dimensional index structure resident in main memory to refer to data objects stored in a database is disclosed. To reduce the amount of accessed index data, the scheme compresses a minimum bounding rectangle ('MBR'). The first step to compress the MBR is to represent the MBR relatively to a reference MBR. The relative representation of an MBR ('RMBR') is coordinates of the MBR represented relative to coordinates of the reference MBR. In addition, quantization may be performed as an additional step for further compression. In this step, the RMBR is quantized using a finite level of quantization chosen from a given set of quantization levels. Alternatively, a proper node size can be chosen to reduce the index search time. The present invention also includes several alternative embodiments of the accessing scheme including whether to eliminate pointer in internal node's entries except the first entry, whether to store a reference MBR in non-root nodes, whether to apply the proposed compression technique by quantization to leaf nodes or not, and whether to place the database in main memory or in disk. Also, the present invention includes an apparatus, a system and a computer readable medium for accomplishing the same scheme as described above.

A cache-conscious version of the R-tree, called the CR-tree, is disclosed. To pack more entries in a node, the CR-tree compresses MBR keys, which occupy substantial part of the index data. It first represents the coordinates of an MBR key relatively to the lower left corner of its parent MBR to eliminate the leading 0's from the relative coordinate representation. Then, it quantizes the relative coordinates with a fixed number of bits to further cut off the trailing less significant bits. Consequently, the CR-tree becomes significantly wider and smaller than the ordinary R-tree. The experimental and analytical results show that the two-dimensional CR-tree performs search faster than the ordinary R-tree while maintaining similar update performance and consuming less memory space.
