In order to extract the key frames more effectively. we propose a key frame extraction method for human motion sequences based on Grey Wolf Optimization (GWO) algorithm. The fitness function is defined with the minimum reconstruction error and the optimal compression rate. The social hierarchy of grey wolves and hunting strategy are simulated to search key frames. https://www.diegojavierfares.com/sale-now-Sterilite-70-Qt-Clear-Plastic-Stackable-Storage-Bin-with-Latching-Lid-4-Pack-p10936-big-savings/
