Embodiment Construction

[0050] In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0051] The first embodiment provided by the present invention is a method for quality analysis of super-resolution images, such as figure 1shown, including steps:

[0052] Step S1, acquiring a source reference image and acquiring a super-resolution image having the same content and number of pixels as the source reference image.

[0053] The source reference image and the super-resolution image have the same content and number of pixels, and the super-resolution image is compared with the source reference image to obtain the quality analysis value of the super-resolution image. Therefo...

Abstract

The invention provides an image quality analysis method and a system of a super-resolution image. The method includes obtaining a source reference image and a super-resolution image with the same content and number of pixels as the source reference image; decomposing the texture component, the structure component and the high frequency component of the source reference image and the super-resolution image respectively; pooling the decomposed texture components, structural components and high frequency components to obtain three pooling fractions corresponding to the three components; three pooling fractions are fused to get the image quality analysis value. The analysis of the invention on the super-resolution image is more objective and accurate than the existing image quality analysis method, and provides important application value for the analysis of the super-resolution image quality obtained after the reconstruction of the low-resolution image in the monitoring field, the satellite image and the medical image.

Description

technical field [0001] The invention relates to the technical fields of digital image processing and computer vision, in particular to an image quality analysis method and system for super-resolution images. Background technique [0002] Image super-resolution is an important research topic in the field of image processing. By performing super-resolution processing on images, the resolution of images can be improved to make images clearer. It has many important applications in image reconstruction, such as: [0003] (1) During the transition period from digital TV (DTV) to high-definition TV (HDTV), only some TV programs will be broadcast in the form of HDTV, and many programs will be broadcast in the form of DTV. Therefore, super-resolution reconstruction technology can be used to convert DTV signals into signals that match HDTV receivers, and improve the compatibility of TV programs; [0004] (2) When collecting military and meteorological remote sensing images, due to th...
