The present disclosure provides an operation-path recommendation method and apparatus. In the present disclosure, by an operation-path recommendation apparatus, a blood vessel graph model is generated based on patient's anatomical information, a plurality of candidate paths between defined start and destination points is extracted; node information on at least one node in each of the candidate paths is extracted; a cost function is applied to each candidate path, based on the extracted node information.

Apparatus and method for recommending operation path

Provided are an apparatus and method of searching a protein active site. The apparatus includes a database which stores information on a plurality of reference active sites, a comparing unit which calculates 3D structural similarities according to the number of overlapping residues, with respect to an input active site and the stored reference active site, and a search unit which searches the reference active site with respect to the input active site according to the similarities. Accordingly, similar active sites can be searched with a low computational complexity, thereby be used for a correct new drug design.

Apparatus and method for searching protein active site

Provided is a system for and method of extracting and clustering information. The system includes a clustering criterion designing unit that reconstructs a plurality of clustering criteria for each layer or applies weights to the plurality of clustering criteria in order to design a new clustering criterion, an input data processing unit that extracts characteristics from input data according to the new clustering criterion, and a clustering unit that performs clustering on the extracted characteristics.

System for and method of extracting and clustering information

A method for constructing a database having image information representing a plurality of images including the steps of: a) calculating L&#xd7;5 number of normalized edge histogram bins to generate L number of edge histograms of a target image, wherein each edge histogram has five normalized edge histogram bins and represents a spatial distribution of five reference edges in a sub-image and L is a positive integer, wherein the reference edges include four directional edges and a non-directional edge; b) non-linearly quantizing the L&#xd7;5 number of normalized edge histogram bins to generate L&#xd7;5 number of quantization index values for the target image; c) storing the L&#xd7;5 number of quantization index values to the database; and d) repeating the steps a) to c) until all of the stored images are processed to thereby construct the database having the image information.
