    摘要: A method and system for face alignment. The method may include obtaining an image processing model set including M (M≥2) candidate models, and obtaining a test image including a target face. The method may also include conducting T (T≥1) stages of model set updating operation. Each stage of the T stages of model set updating operation may include conducting a performance evaluation to each candidate model of the image processing model set with respect to the test image, and updating the image processing model set by excluding at least one model from the image processing model set based on the performance evaluation. The method may further include designating, after completing the T stages of model set updating operation, at least one candidate model of the image processing model set as a target model, and determining, based on the target model, a result shape as a shape of the target face.
