Problems solved by technology

In the actual shooting, it will be affected by external factors (such as noise, light, angle, etc.), resulting in a large number of faces with poor quality and non-frontal postures in the captured face images, which have brought difficulties to face recognition. A lot of interference, resulting in unsatisfactory face recognition, for example, misidentifying A in the image as B

Abstract

The invention discloses an end-to-end face image generation method based on a conditional generative adversarial network. The method comprises the following specific steps: inputting a plurality of preprocessed real face images to a generator, and carrying out encoding, carrying out transcoding and decoding processing on the input real face images by the generator to generate a composite image fitting real image distribution; inputting the synthesized image of the obtained real image distribution and a plurality of originally input preprocessed real face images into a discriminator to obtain the real probability of the real face images and the real probability of the synthesized image, and iteratively updating the parameters of the generator and the discriminator until the parameters converge so as to determine a model constructed by the generator and the discriminator; and inputting a to-be-synthesized side posture human face image into the model, and obtaining a generated front posture human face image through one-time forward transmission. The method is high in efficiency, can process extreme illumination conditions and multi-angle side posture transformation, and does not needto estimate a three-dimensional model or two-dimensional feature points of a human face.

Description

technical field [0001] The invention belongs to the technical field of image processing, and mainly relates to an end-to-end system and method for synthesizing a frontal face from a side face based on a conditional generative confrontation network. Background technique [0002] In recent years, face recognition technology has developed rapidly, and its application fields are becoming wider and wider. In the actual shooting, it will be affected by external factors (such as noise, light, angle, etc.), resulting in a large number of faces with poor quality and non-frontal postures in the captured face images, which have brought difficulties to face recognition. A large amount of interference causes unsatisfactory face recognition results, for example, A in the image is mistakenly identified as B. These problems will bring great inconvenience to the follow-up work. Therefore, how to generate a clear and recognizable high-quality face image of the frontal pose from the face imag...
