Abstract: This application discloses example image generation methods. One example method includes obtaining a target vector. The target vector can then be separately input to a first generator and a second generator to correspondingly generate a first sub-image and a second sub-image, where the first generator is obtained by a server by training, based on a low-frequency image and a first random noise variable that satisfies normal distribution, a first generative adversarial network (GAN), the second generator is obtained by the server by training, based on a high-frequency image and a second random noise variable that satisfies the normal distribution, a second GAN, and a frequency of the low-frequency image is lower than a frequency of the high-frequency image. The first sub-image and the second sub-image can then be synthesized to obtain a target image.

Abstract: Embodiments of the present invention provide a terminal device and a method for quickly starting a program. The terminal device includes a device body, where a front touch-sensitive display is located on a front surface of the device body, and an auxiliary touch device is located on a back surface or a side surface of the device body. The device body supports a controller and a memory. The controller is configured to drive the auxiliary touch device, generate a corresponding touch signal according to a touch action of a user that is received by the auxiliary touch device, determine a user event according to the touch signal, run a corresponding executable program according to mapping between the user event and the executable program in the memory. The technical solutions of the present invention can implement quick start of the executable program corresponding to the touch action of the user.
