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
