Lina Jin, a researcher of Department of Signal Processing, Tampere University of Technology, Finland, have been visiting Media Communication Lab since October 2013. She kindly took some time to share her research experience with us.

Could you talk about your research interest?

My research interests mainly focus on image and video quality metrics, human vision modeling, stereoscopic video quality metrics, perceptual image coding, image enhancement and super resolution.  Modern image and video system typically consist of several processing stages, such as acquisition, compression, storage, transmission, enhancement, and reproduction. In ach stage, noised might be introduced, resulting in a degradation of visual quality. Therefore, quality assessment plays an important role in the design or optimization for an image processing system. The objective quality assessment aims at automatically estimating input image or video quality and highly correlating to subjective judgment .To design an effective and efficient quality assessment algorithm, we need deeply understand how human visual system (HVS) perceives image quality and how these properties could be simulated. The research I am currently working on in MCL is related to quality assessment based image enhancement and super resolution for UHDTV.

Please share your thoughts about our lab.

It’s a great honor for me towork at MCL group with Prof. Kuo and group members. MCL is one of world famous labs in the field of multimedia.  Now, MCL group is conducting academic research on cutting-age topics, such as computer vision, machine learning, and image processing.

Every Friday, MCL group holds an academic seminar. During the seminar, Prof. Kuo shares his research experiences to thegroup members, and one of his studentsgives an one-hour high-quality presentation to share and discuss his or her recent research work with others. I am very enjoyed the seminar and has learnt a lot from Prof. Kuo’s talks and students’ presentations.
