Problems solved by technology

[0003] However, in a digital image, pixels with higher definition also mean higher noise, resulting in higher noise in the final composite image, which contains more noise and gives people a strong graininess.

Embodiment Construction

[0050] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.

[0051] When the image acquisition device collects images, among the objects included in the field of view of the camera of the image acquisition device, some objects must be closer to the camera, and some objects are farther away from the camera. Therefore, when the camera of the image acquisition device captures images, it is impossible for the camera to focus on all objects in the field of view at the same time, which eventually leads to the sharpness of the focused items...

Abstract

The embodiment of the invention relates to an image definition determination method and device, equipment and a storage medium. The method comprises the following steps: respectively carrying out edge-preserving and noise-reducing processing on a first original image and a second original image to obtain a first image after edge-preserving and noise-reducing processing and a second image after edge-preserving and noise-reducing processing; extracting first image detail data from the first image after edge-preserving and noise-reducing, and extracting second image detail data from the second image after edge-preserving and noise-reducing; and determining a definition comparison result of the first original image and the second original image according to the first image detail data and thesecond image detail data. By adopting the technical scheme, when definition comparison is carried out on the two original images, edge-preserving and noise-reducing processing is firstly carried out on the two original images, and then definition comparison is carried out on the two images after edge-preserving and noise-reducing processing, so that the interference of noise in the original imageson definition comparison is reduced, and the accuracy of definition comparison is improved.

Description

technical field [0001] The embodiments of the present application relate to the technical field of image processing, and in particular, to a method, device, device, and storage medium for determining image definition. Background technique [0002] When performing multi-focus image fusion, two original images are usually fused in blocks. Specifically, relatively high-resolution pixels (or pixel blocks) in the two original images are fused to obtain an overall clear image. [0003] However, in a digital image, pixels with higher definition mean higher noise, which leads to higher noise in the final composite image, which contains more noise and gives people a strong sense of graininess. Contents of the invention [0004] Embodiments of the present application provide a method, device, device, and storage medium for determining image sharpness, aiming at reducing the interference of image noise on sharpness comparison. [0005] The first aspect of the embodiment of the pres...
