  • Usually, during slaughter, the meat is divided into large chunks by part after deboning. The meat chunks are inspected for the presence of needles with an X-ray scanner. Although needles in the meat chunks are easily detectable, they can also be found in trimmings and meat offals, where meat skins, fat chunks, and pieces of meat from different parts get agglomerated. Detection of needles in trimmings and meat offals becomes challenging because of many needle-like patterns that are detected by the X-ray scanner. This problem can be solved by learning the trimmings or meat offals using deep learning. However, it is not easy to collect a large number of learning patterns in trimmings or meat offals. In this study, we demonstrate the use of deep convolutional generative adversarial network (DCGAN) to create fake images of trimmings or meat offals and train them using a convolution neural network (CNN).

  • 본 논문에서는 기존의 쿠폰의 사용자 편의성을 극대화하기 위하여, NFC를 기반으로 하는 모바일 쿠폰 추천 시스템을 제안한다. 기존의 쿠폰은 사용자에게 무작위로 정보를 제공하고, 종이 쿠폰의 경우 분실의 가성능과 여러 장을 소지해야 하는 단점이 있었다. 따라서 본 논문에서는 NFC기반으로 사용자에게 마일리지를 판매자의 홍보 수단으로 제공하는 한편 이를 이용해 얻어지는 판매자들의 매장 이용 현황의 유사도를 분석하여, 비슷한 유사도를 보이는 사용자를 기반으로 판매자의 매장의 쿠폰을 추천하는 쿠폰 추천 시스템을 구현하였다
