Problems solved by technology

However, when a series of operations are performed on the image to convert it from a low-resolution image to a high-resolution image, it often causes image distortion, making it unable to meet actual needs. For example, after a series of operations, the low-resolution human After the face image is converted into a high-resolution face image, the face is deformed, resulting in incorrect recognition

Abstract

The present application discloses methods and apparatus for generating images. A specific implementation of the method includes: acquiring a face image to be processed, wherein the image resolution of the face image to be processed is lower than a preset first resolution threshold; inputting the face image to be processed The pre-trained generation model generates processed face images. The above-mentioned generation model uses a loss function to update model parameters during the training process, and the loss function is based on the image group composed of face sample images and face generation images as positive samples The probability of the data is determined. This embodiment improves the authenticity of the generated face images.

Description

technical field [0001] The present application relates to the field of computer technology, specifically to the field of image processing, and in particular to methods and devices for generating images. Background technique [0002] With the rapid development of high-definition display devices, people's demand for high-resolution images and videos is increasing. At this stage, low-resolution images can be transformed into high-resolution images through a variety of methods, such as difference-based methods, reconstruction-based methods, learning-based methods, and so on. However, when a series of operations are performed on the image to convert it from a low-resolution image to a high-resolution image, it often causes image distortion, making it unable to meet actual needs. For example, after a series of operations, the low-resolution human After the face image is converted into a high-resolution face image, the face is deformed, resulting in incorrect recognition. Therefo...
