Key-Frame Extraction Based on HSV Histogram and Adaptive Clustering
Algorithm 2
AGNES clustering algorithm for key-frame extraction.
(1) | Initialization: each video frame is put into an initial cluster and converted into a one-dimensional vector | (2) | Optimal cluster number: calculate the maximum SC index for the value of k | (3) | Repeat | (4) | Calculate the distance between any two adjacent clusters | (5) | Merge two nearest clusters to generate a new cluster | (6) | Until the expected k clusters are generated or other termination conditions are satisfied |
