Abstract: This invention provides an object tracing apparatus that traces an object in a video obtained by an image capturing apparatus, comprising a tracking unit that tracks the object in a frame in the video and obtains track data indicating consecutive appearances of the object, and a tracing unit that generates trace information indicating which object ID each track ID belongs to, by associating a track ID obtained via tracking by the tracking unit with an object ID for uniquely identifying an object, wherein the tracing unit, on a basis of a coexistence possibility relating to imaging time between a track ID associated with one or more existing object IDs and target track data without an associated object ID, determines which object ID the target track data belongs to.

Abstract: An image processing apparatus performs an inspection on an assembly component with use of one or more images of an assembling work, and includes a work determination unit configured to determine, from the one or more images, one or both of a start frame and an end frame of assembling work captured at a change point of the assembling work, a selection unit configured to select frames to be inspected from the one or more images based on a result of the determination by the work determination unit, and an inspection unit configured to perform an inspection on the frames selected by the selection unit.

Abstract: An information processing apparatus generates authentication data that can be used for authentication of a first object that is included in a captured image captured by a first image capturing apparatus and has been authenticated by a first authentication apparatus corresponding to the first image capturing apparatus; and causes the authentication data to be reflected to an authentication database (DB) of at least one authentication apparatus included in a plurality of authentication apparatuses. The apparatus generates second authentication data corresponding to a second capturing condition differing from a first capturing condition corresponding to first authentication data that is included in the authentication DB of the first authentication apparatus and was used when authenticating the first object.

Abstract: A process for preparing 7-benzylpurine derivatives is provided. An acetylpurine nucleoside is reacted with a benzyl halide to benzylate the 7-position of the purine base, and an acid is then added to the reaction mixture to hydrolyze the glycoside bond. The 7-benzylpurines may be used to prepare 9-substituted purine derivatives.

Abstract: Herein is disclosed a novel and industrially advantageous process for synthesizing acyclic nucleosides such as acyclovir and ganciclovir from ribonucleosides, which process comprises adding an acid catalyst and an acid anhydride to a solution of a ribonucleoside such as guanosine and an ester derivative of an acyclic sugar, and heating the mixture, whereby a transglycosilation reaction takes place between the ribose moiety of the ribonucleoside and the ester derivative of the acyclic sugar.Herein is also disclosed an industrially favorable method for the separation of 9-substituted purine nucleosides which are important intermediates for the synthesis of acyclic nucleosides such as acyclovir, ganciclovir, and the like from ribonucleosides, which method comprises crystallizing only the 9-isomer from a solution or suspension containing both a 9-substituted purine nucleoside and a 7-substituted purine nucleoside by cooling the solution or/and by adding a crystallizing solvent thereto.

Abstract: Nucleoside derivatives such as 2'-deoxy-2'-bromo-5'-O-acetyl-5-methyluridine, etc., are important intermediates which can be converted into nucleoside derivatives, such as 3'-azido-3'-deoxythymidine, etc., which are useful as medicines.

Abstract: A process for preparing a 2', 3'-dideoxy-2',3'-didehydropyrimidine nucleoside comprising reacting the pyrimidine ribofuranoside with a trialkyl orthoester to yield the 2',3'-O-alkoxyethylidene derivative; which is reacted with hydrogen bromide in acetic acid or acetyl bromide to yield the 2-deoxy-2'-bromo-3'-acetyl-pyrimidine nucleoside; which is then reduced with zinc to yield the 2',3'-olefin of the pyrimidine nucleoside.
