TIQA-PSI: Toolbox for perceptual Image Quality Assessment of Pan-Sharpened Images

open access: yesSoftwareX, 2023
A Pan-Sharpening (PS) technique integrates spatial details of a high-resolution panchromatic (PAN) image with spectral information of a low-resolution multi-spectral (MS) image, creating a single high-resolution color image.

A survey on IQA

open access: yes, 2021
Image quality assessment(IQA) is of increasing importance for image-based applications. Its purpose is to establish a model that can replace humans for accurately evaluating image quality. According to whether the reference image is complete and available, image quality evaluation can be divided into three categories: full-reference(FR), reduced ...
