Problems solved by technology
[0003] The existing technology is usually based on a single frame of low-resolution face image, and through super-resolution processing, a super-resolution face image is obtained. The super-resolution face image obtained in this way has face information missing, and the super-resolution face image cannot be guaranteed. The identity information in the high-resolution face image is consistent with the identity information in the single-frame low-resolution face image

Embodiment Construction
[0087] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings. The specific operation methods in the method embodiments may also be applied to the apparatus embodiments or the system embodiments. It should be noted that, in the description of this application, "a plurality" is understood as "at least two". "And / or", which describes the association relationship of the associated objects, means that there can be three kinds of relationships, for example, A and / or B, which can mean that A exists alone, A and B exist at the same time, and B exists alone. A and B are connected, which can be expressed as two cases: A and B are directly connected and A and B are connected through C. In addition, in the description of this application, words such as "first" and "second" are only used for the purpose of distinguishing and descri...

The invention discloses an image generation method and device and electronic equipment, and the method comprises the steps: sequentially inputting N frames of low-resolution face images into a first network model through an iteration mode, training the first network model, and constraining the training process through the output loss of the first network model, and recording the trained first network model as a second network model until the training result of the first network model converges, and performing super-resolution processing on the multi-frame low-resolution face image of any target by the second network model to obtain a super-resolution face image consistent with the multi-frame low-resolution face image in identity. Based on the method, the problem that the identity information in the obtained super-resolution face image and the identity information of the single-frame low-resolution face image cannot be ensured to be consistent when super-resolution processing is carried out based on the single-frame low-resolution face image can be solved.
Description
technical field [0001] The present application relates to the technical field of face recognition, and Envoy relates to an image generation method, device and electronic device. Background technique [0002] With the rapid development of science and technology and the arrival of the era of big data, information security has become more and more important. As a safe, non-contact, convenient and efficient identity information authentication method, face recognition has been widely used in all aspects of social life. However, in a relatively large surveillance scene, the size of the face appearing in the video is usually small and the image definition is low, which is difficult to meet the needs of face recognition. Therefore, face super-resolution technology becomes more and more important. The face super-resolution technology essentially adds high-frequency features to low-resolution face images to generate high-resolution face images. [0003] The prior art is usually base...
