Target Image Video Search Based on Local Features
share
This paper presents a new search algorithm called Target Image Search based on Local Features (TISLF) which compares target images and video source images using local features. TISLF can be used to locate frames where target images occur in a video, and by computing and comparing the matching probability matrix, estimates the time of appearance, the duration, and the time of disappearance of the target image from the video stream. The algorithm is applicable to a variety of applications such as tracking the appearance and duration of advertisements in the broadcast of a sports event, searching and labelling painting in documentaries, and searching landmarks of different cities in videos. The algorithm is compared to a deep learning method and shows competitive performance in experiments.
