The invention discloses a method for compounding face fake portrait\fake photo based on support vector return. The method comprises steps as follows: (1) partitioning database sample set; (2) randomly taking a photo\portrait from a photo\portrait testing set; (3) generating fake portrait\fake photo initial estimate corresponding to the randomly-taken photo\portrait; (4) generating a training face photo\portrait block set; (5) generating a support vector return model between the training face photo\portrait block set and a training face portrait/photo block set; (6) generating fake portrait\fake photo high frequency corresponding to the randomly-taken photo\portrait; and (7) generating the final fake portrait\fake photo. The invention combines the initial estimate and the high frequency to generate the fake portrait\fake photo, so as to enable the generated fake portrait\fake photo to be clearer and improve the discrimination when searching the fake portrait\fake photo. The invention adopts the method based on support vector return, and the method can also be used in small sample issues.
