description The invention discloses a micro-action chronological parameter acquisition method and device and a medium, and belongs to the field of medical video understanding and recognition. The method comprises the following steps: acquiring swallowing contrast video data; extracting video features according to the swallowing contrast video data; the video features comprise RGB features and optical flow features; inputting the extracted video features into an attention mechanism with a variable window size, performing feature enhancement processing, and outputting visual enhancement features; and inputting the vision enhancement features into a coarse-to-fine two-stage micro-action positioning network, and outputting a swallowing contrast micro-action positioning and recognition result. According to the method, the time sequence action positioning technology in video understanding is utilized, automatic positioning on the time sequence of the swallowing radiography video is achieved, the time sequence information of al
