Problems solved by technology
However, due to the moderate light intensity and single shooting equipment in the bank branch scene, and only close-up face photos of users are collected, the reconstructed pictures in this way have unreasonable high-frequency details such as bright spots and uneven texture changes. , so that the reconstructed photos have a low resolution, which is still difficult to meet the needs of practical business applications.

The embodiment of the invention provides an image generation method, device and equipment, which can be used in the financial field. The method comprises the following steps: acquiring a reference image block of an initial image; randomly selecting two first neighbor image blocks from a neighbor image block set corresponding to the reference image block; determining a projection point of the reference image block on the feature line; calculating a first projection point and a corresponding second projection point of the reference image block on the feature line according to the first neighbor image block and the second neighbor image block under the condition that the projection point of the reference image block on the feature line is in a preset projection range; obtaining a target image block corresponding to the reference image block based on the first projection point and the second projection point; and obtaining a target image corresponding to the initial image according to the target image block. According to the embodiment of the invention, the reconstruction of a photo containing unreasonable highlight spots and unsmooth textures can be avoided, and the resolution of the reconstructed photo is improved.
Description
technical field [0001] The present application relates to the field of computer vision, in particular to an image generation method, device and equipment. It should be noted that the image generation method, device and equipment disclosed in this application can be used in the financial field, and can also be used in any field other than the financial field. The application fields of the image generation method, device and equipment disclosed in this application are not limited . Background technique [0002] The user photos stored in the line may be low-resolution due to factors such as shooting pixels and image compression, so it is difficult to meet the needs of actual business applications based on these photos. Therefore, increasing the resolution of photos is becoming more and more important. [0003] In the prior art, a face image super-resolution method based on the recent feature line manifold learning is mainly used to reconstruct a high-resolution image. Howeve...
