This paper proposes a video retrieval method that detects frame sections that correspond to shots in a query (video segment) with single frame level accuracy. The method adopts the coarse-to-fine strategy to decrease the processing time and the memory consumption, dynamic threshold with initial ranges for small segments is proposed to detect the exact beginning and end of each corresponding frame section to each shot in a query. Experiments on real videos show that our method can achieve accurate video detection with exact frame position while reducing processing time and memory consumption.
