Infant image composition method and device

The invention discloses an infant image composition method and device, and belongs to the technical field of image processing. The composition method includes the steps that feature point locating is conducted on a father source image, a mother source image and an infant source image to obtain feature vectors of the source images; a standard infant template is utilized to restrict the feature vectors of the source images so as to obtain a target infant shape; transformation processing is respectively conducted on the source images according to the target infant shape to obtain three transformation images; the three transformation images are fused to obtain a target infant image. In the process of shape composition, the standard infant template is adopted to conduct restriction, large fusion weight can be arranged to a father and a mother, so that appearance of an infant tends to be like the father and the mother; with the restriction effect of the standard infant template, the problems of distortion and stretching of the facial form of the composited infant are solved, and visual quality of the composited infant photo is improved.
