题目: Perceptual Considerations for Visual Quality Evaluation and Beyond主讲人: Prof. Weisi Lin, Nanyang Technological University, Singapore时间: 5 月 30 日下午 2 点地点：软件楼 102 第二会议室联系人：颜波（byan@fudan.edu.cn)
Abstract:
It is beneficial to incorporate perceptual criteria in visual signal (be it naturally captured or computer generated) evaluation and processing processes, since the human visual system (HVS) is the final receiver and appreciator for most processed visual signal, and as a result of the evolution, the HVS has developed unique characteristics. Significant research effort has been made toward modelling the relevant HVS’ mechanism, and to apply the models to various situations.In this talk, we will first introduce the major considerations associated with perceptual visual quality metrics, to be in line with the HVS perception, as well as the new research and development work in this field (e.g., the emerging machine learning based methodology). Then, we will discuss the related perceptual issues in other applications, such as image retargeting, video coding, and computer graphics. The talk will also give our opinions for future research directions and development in the related areas.
