Abstract: The present disclosure provides a pedestrian tracking method and device, and a computer-readable storage medium, and relates to the field of communication technology. The pedestrian tracking method includes: performing pedestrian trajectory analysis on video pictures acquired by preset surveillance cameras to generate a pedestrian trajectory picture set (S110); performing multi-modal feature extraction on the pedestrian trajectory picture set, and forming a pedestrian multi-modal database (S120); and inputting the pedestrian multi-modal database to a trained multi-modal identification system, and performing pedestrian tracking to generate a movement trajectory of a pedestrian in the preset surveillance cameras (S130).

Abstract: A membrane-forming composition, soft and hard capsules prepared based on the composition and the preparation methods are described. The membrane-forming composition includes pullulan polysaccharide, gellan gum, amino acid moisturizing agent, anti-hygroscopic agent and so on. It is suitable for the fabrication of hard or soft capsules. The membrane-forming composition can gelate without alkali metal ions. It has a high moisture retention rate which makes it not easy to take up moisture and turn soft in high humid environment, and it will not turn yellow during long time storage. Furthermore, the membrane-forming composition is made up of pure natural materials.
