Publication number: 20190005653Abstract: A method includes acquiring, by a device, encoded image data corresponding to an original image. The method includes decoding, by the device, the encoded image data. The method included acquiring, by the device, a foreground extraction target frame and an encoding parameter associated with an encoding process of the original image based on decoding the encoded image data. The method includes extracting, by the device, a first candidate foreground associated with the foreground extraction target frame based on the encoding parameter. The method includes extracting, by the device, a second candidate foreground associated with the foreground extraction target frame based on a preset image processing algorithm. The method includes determining, by the device, a final foreground associated with the foreground extraction target frame based on the first candidate foreground and the second candidate foreground.Type: ApplicationFiled: July 2, 2018Publication date: January 3, 2019Applicant: SAMSUNG SDS CO., LTD.Inventors: Jung Ah CHOI, Jin Ho CHOO, Jong Hang KIM, Jeong Seon YI, Ji Hoon KIM
