description The invention discloses a method and a system for improving image face individual registration performance by utilizing joint registration. The method comprises the following steps of: 1, forming a face calibration point set according to face region rectangles of face individuals in a group of images; 2, obtaining a reference face point set by utilizing the front face training set, and performingstandardized operation on the reference face point set and the face calibration point set in the step 1; 3, obtaining a preliminary fitting result set of the face of the group of images; 4, determining a distortion result set of the preliminary fitting result set according to the parameters; and step 5, updating the reference face by using the distortion result set, and iterating from the step 3 to the step 5 to complete a joint registration process. The maximum iterations are used as termination metrics. The method provided by the invention belongs to the latter and is different from the previous method in that a ref
