Sperm tail detection method and system based on neural network

The invention discloses a sperm tail detection method and system based on a neural network. The method comprises the following steps: collecting a sperm image; segmenting the sperm image through a first neural network unit to generate a segmented image; extracting sperm head coordinates and head direction data of the sperm image through a second neural network unit; extracting a sperm tail coordinate set of the segmented image based on the sperm head coordinates and the head direction data; and generating a detection result containing sperm tail length information based on the sperm tail coordinate set and the segmented image. According to the invention, the head region image and the tail region image of the sperm image are accurately extracted through the neural network algorithm to improve the segmentation precision, and the sperm tail coordinate set is generated by traversing the skeleton points in the skeleton map corresponding to the tail region image. Therefore, accurate sperm tail length information is
