Underwater image enhancement plays a critical role in marine industry. Various algorithms are applied to enhance underwater images, but their performance terms of perceptual quality has been little studied. In this paper, we investigate five popular and output quality. To end, have created benchmark, including images enhanced by different ground truth obtained human perception experiments. We s...

Comparing self-assessed indicators of subjective outcomes such as health, work disability, political efficacy, job satisfaction, etc. across countries or socio-economic groups is often hampered by the fact that different groups use systematically different response scales. Anchoring vignettes have been introduced as an effective tool to correct for such differences. This paper develops an integ...

The main thesis developed and tested in this article is that development stage plays an important moderating role in determining both objective and subjective performance outcomes in free/open source software (F/OSS) projects. This contention is supported by an empirical study of 67 F/OSS projects, with results indicating that subjective performance assessments are calibrated to different objec...
