Effective Keyframe Extraction from Personal Video by Using Nearest Neighbor Clustering
Chaohui Lv, Yiyang Huang · 2018
Keyframe extraction is one of the most important issue for video understanding and retrieval researches, especially with the rapid growth of uploaded personal video numbers. The frame clustering method has been a theoretically mature method in keyframe extraction. However, the process of clustering often takes long time that seems not very practical. In this paper, we propose an improved clustering method based on video feature, and it proves to be effective in keyframe extraction.
