The apparatus includes: a weighted feature extractor configured to extract a weighted feature from an input image and generate a weighted descriptor to which a feature of a salient region is applied; a dictionary constructor configured to construct a dictionary composed of images with different characteristics of one object using the weighted descriptor to which the feature of the salient region is applied by the weighted feature extractor and store the dictionary in a database (DB); and a coefficient estimator and ID determiner configured to apply sparse representation for estimating a coefficient that allows an object to be reconstructed as much as possible with a few linear combinations of candidate objects of a target object constituting the dictionary, and perform identification using an error between a target and the reconstructed object.

Apparatus and method for re-identifying object in image processing

A non-biodegradable endodontic sealant composition comprises the reaction product of a first paste and a second paste. Either paste or both pastes include one or more of: unmodified HEMA and bioglass. The first paste includes a first polymerizing agent and the second paste includes a second polymerizing agent. A method for making the composition comprises preparing the first paste and second paste and combining the pastes under conditions to achieve a polymerization reaction initiated by a reaction between the polymerizing agents. The combining step is performed under conditions for achieving a setting time that is in a range of about 1 minute to about 1 hour. A method for treating humans having a voided region into which no re-growth will occur comprises administering the composition to the affected area, preferably to an area where tissue, tooth, or bone are not intended to re-grow.
