Publication number: 20110231131Abstract: Disclosed herein is a forged seal imprint checking method which includes a step ST-101 of generating a reference seal imprint from a genuine seal (ST-110) and a step ST-121 of comparing a compared seal imprints with the reference seal imprint to calculate characteristic values of the compared seal imprint with respect to the reference seal imprint (ST-140). According to experimental results, forged seal imprints obtained by seals forged by etching a zinc plate or a resin plate can be recognized and forged seal imprints generated by seals forged through computer copy can be also recognized. Accordingly, an objective basis on which it can be determined whether seal imprints on documents are forged in civil and criminal cases can be provided to prevent errors which may be generated when seal imprints are inspected with the naked eyes or microscopes.Type: ApplicationFiled: November 30, 2010Publication date: September 22, 2011Inventors: Joong LEE, Young Su Lee, Jun Suk Kim, Ki Woong Moon, Byung Wook Park

Patent number: 8020982Abstract: A bubble removing apparatus for removing air bubbles in ink to be supplied to a printer head of an inkjet printer and a method of removing the air bubbles are provided to provide a smooth flow of ink to the inkjet printer head. When an air bubble removing operation is performed, ink in an ink tank is moved towards the printer head through a filter unit by operating the pump in a forward direction, and the ink that has moved towards the printer head is returned to the ink tank through the filter unit by operating the pump in a reverse direction. Air bubbles trapped in the filter unit are moved to the ink tank due to the operation of the pump in the reverse direction and are removed in the ink tank by the gravitational force, and thereby a smooth flowing ink supply can be provided to the printer head.Type: GrantFiled: October 2, 2007Date of Patent: September 20, 2011Assignee: Samsung Electronics Co., Ltd.Inventors: Il-ju Mun, Young-su Lee

Patent number: RE42516Abstract: A method of coding a moving picture reduces blocking artifacts. The method includes defining pixel sets S0, S1, S2 around a block boundary, selectively determining a deblocking mode as a default mode or a DC offset mode depending on the degree of blocking artifacts. If the default mode is selected, frequency information is obtained around the block boundary per pixel using a 4-point DCT kernel, for example, a magnitude of a discontinuous component belonging to the block boundary is replaced with a minimum magnitude of discontinuous components belonging to the surroundings of the block boundary in the frequency domain and the replacing step is applied to the spatial domain. If the DC offset mode is selected and a determination is made to perform DC offset mode, the blocking artifacts in a smooth region are removed in the DC offset mode.Type: GrantFiled: September 7, 2007Date of Patent: July 5, 2011Assignee: Video Enhancement Solutions, LLCInventors: Hyun Mun Kim, Jong Beom Ra, Sung Deuk Kim, Young Su Lee
