In this article, we have reviewed the reasons why we (collectively) want to love or leave the
venerable (but perhaps hoary) MSE. We have also reviewed emerging alternative signal …

This Lecture book is about objective image quality assessment—where the aim is to provide
computational models that can automatically predict perceptual image quality. The early …

We propose a tone map** operator that can minimize visible contrast distortions for a
range of output devices, ranging from e-paper to HDR displays. The operator weights …

Abstract Image Quality Assessment (IQA) is a very difficult task, yet highly important
characteristic for evaluation of the image quality. Widely popular IQA techniques, belonging …

We present an original error-diffusion method which produces visually pleasant halftone
images while preserving fine details and visually identifiable structures present in the …

Despite the increase in email and other forms of digital communication, the use of printed
documents continues to increase every year. Many types of printed documents need to be" …

Publisher Summary This chapter examines objective criteria for the evaluation of image
quality as perceived by an average human observer. The focus is on image fidelity, ie, how …

With the development of computer technology and network technology, a large amount of
printed documents are converted to the electronic documents and spread on internet. When …

In recent years, digital copies of paper documents are used widely with the prevalence of
various online services. As a result, it is critical to validate the authenticity of the uploaded …

Perceptual image coding requires an effective image quality metric, yet most of the existing
metrics are complex and can hardly guide the compression effectively. This paper proposes …
