Publication number: 20240078710Abstract: Disclosed herein are a method, an apparatus and a storage medium for encoding/decoding using a transform-based feature map. An optimal basis vector is extracted from one or more feature maps, and a transform coefficient is acquired through a transform using the basis vector. The basis vector and the transform coefficient may be transmitted through a bitstream. In an embodiment, one or more feature maps are reconstructed using the basis vector and the transform coefficient, which are decoded from the bitstream.Type: ApplicationFiled: September 1, 2023Publication date: March 7, 2024Applicant: Electronics and Telecommunications Research InstituteInventors: Youn-Hee KIM, Jooyoung LEE, Se-Yoon JEONG, Jin-Soo CHOI, Dong-Gyu SIM, Na-Seong KWON, Seung-Jin PARK, Min-Hun LEE, Han-Sol CHOI

Publication number: 20240073416Abstract: The present invention relates to an apparatus and method for encoding and decoding an image by skip encoding. The image-encoding method by skip encoding, which performs intra-prediction, comprises: performing a filtering operation on the signal which is reconstructed prior to an encoding object signal in an encoding object image; using the filtered reconstructed signal to generate a prediction signal for the encoding object signal; setting the generated prediction signal as a reconstruction signal for the encoding object signal; and not encoding the residual signal which can be generated on the basis of the difference between the encoding object signal and the prediction signal, thereby performing skip encoding on the encoding object signal.Type: ApplicationFiled: November 6, 2023Publication date: February 29, 2024Applicants: Electronics and Telecommunications Research Institute, Kwangwoon University Industry-Academic Collaboration Foundation, Universily-lndustry Cooperation Group of Kyung Hee UniversityInventors: Sung Chang LIM, Ha Hyun LEE, Se Yoon JEONG, Hui Yong KIM, Suk Hee CHO, Jong Ho KIM, Jin Ho LEE, Jin Soo CHOI, Jin Woong KIM, Chie Teuk AHN, Dong Gyu SIM, Seoung Jun OH, Gwang Hoon PARK, Sea Nae PARK, Chan Woong JEON

Patent number: 6571781Abstract: The present invention relates to a fuel injecting apparatus for an internal combustion engine, in which exhaust gas is applied to the injection of fuel. According to the fuel injecting apparatus, a portion of hot exhaust gas is introduced in front of the outlet of the fuel injector allowing hot exhaust gas to promote the fine particle formation and vaporization of fuel thereby enhancing efficiency of fuel. Again, a portion of exhaust gas can be circulated into the combustion chamber to restrict the production of nitrogen oxide. Also, exhaust gas re-introduced into the combustion chamber through the EGR line is cooled by heat of vaporization of fuel injected from the fuel injector thereby advantageously relieving the installation of an additional cooling system for cooling exhaust gas which is re-circulated into the combustion chamber.Type: GrantFiled: June 12, 2001Date of Patent: June 3, 2003Assignee: Korea Institute of Machinery and MaterialsInventors: Gyu Baek Cho, Dong Soo Jeong

Patent number: 6188104Abstract: A trench DMOS device has a gate insulating layer on the bottom and sidewalls of the trench. The upper edges of the trench have an impurity injection region and are rounded. In addition, a first conductive layer is formed on the gate insulating layer, and a second conductive layer is formed on the first conductive layer and filled in the trench. The second conductive layer has different crystallization from the first conductive layer. As such the first conductive layer acts as a buffer between the gate insulating layer and the filled in second conductive layer. A method for fabricating a trench DMOS device includes the steps of forming an epitaxial layer on a semiconductor substrate. Then an impurity is injected into the epitaxial layer to form an impurity injection region. Then a trench is formed in the semiconductor substrate passing through the impurity injection region. Then a dry etching process is used to round the upper edges of the trench.Type: GrantFiled: March 27, 1998Date of Patent: February 13, 2001Assignee: Samsung Electronics Co., LtdInventors: Mun-Heui Choi, Dong-Soo Jeong
