Background Initialization by Spatiotemporal Similarity
박구만,Park, Goo-Man The Korean Institute of Broadcast and Media Engine 2007 방송공학회논문지 Vol.12 No.3
A background initialization algorithm based on the spatiotemporal similarity measure in a motion tracking system is proposed. From the accumulated difference between the base frame and the other frames in a subinterval, the regions affected by moving objects are located. The median is applied over the subsequence in the subinterval in which co-located regions share the similarity. The outputs from each subinterval are filtered by second stage median filter. The proposed method showed good results even in the busy and crowded sequences where the real background does not exit.

Deep learning is used in various fields, especially the YOLO algorithm, which is one of the many deep-running frameworks, has very fast speed and accuracy that does not lag behind other frameworks. This paper includes a central control system for detecting and recognizing vehicle license plate using YOLO, identifying the vehicle type of the parked vehicle on the parking lot, and checking the parking position of each vehicle in the parking lot based on the recognized car number We intend to facilitate comprehensive parking vehicle management.

본 논문에서는 방송에 사용되는 주파수 이용 현황을 조사, 분석하였다. 주파수 이용 기본 정비 방안과 세부추진 방안을 분석하여 바람직한 활용방안을 제시하였다. 주파수 할당을 위한 경매 제도를 분석하여 DTV 스펙트럼의 재활용 방안으로서의 적합성을 검토하였다. DTV의 리턴채널 가능성도 분석하였다. 분석한 결과를 토대로 3가지 활용방안을 제시하고 각 방안의 장단점도 언급하였다.
