Short Bio

My name is Jiheng Wang and I am currently a Post-Doctoral Fellow worked with Professor Zhou Wang. I obtained my Ph.D. degree (2011-2016) in the Department of Electrical and Computer Engineering at University of Waterloo under the supervision of Professor Zhou Wang. I completed a Master Degree (2008-2010) in the Department of Statistics and Actuarial Science at University of Waterloo under the supervision of Professor Guangzhe Fan and of Professor Zhou Wang.


Research Interests

  • 3D image and video quality assessment

  • Statistical learning and dimensionality reduction


    Waterloo IVC 3D Image Quality Database

    The Waterloo IVC 3D Image Quality database Phase I is created from 6 pristine stereoscopic image pairs (and thus their corresponding single-view images), all collected from the Middlebury Stereo 2005 Datasets. Each single-view image was altered by three types of distortions:additive white Gaussian noise contamination, Gaussian blur, and JPEG compression. Each distortion type had four distortion levels, where the distortion control parameters were decided to ensure a good perceptual separation. The single-view images were employed to generate distorted stereopairs, either symmetrically or asymmetrically. Altogether, there are totally 78 single-view images and 330 stereoscopic images. The Waterloo IVC 3D Image Quality database Phase II with more diverse image content is created from 10 pristine stereoscopic image pairs (and thus their corresponding single-view images). Each single-view image was altered by the same three types of distortions and each distortion type had the same four distortion levels. There are totally 130 single-view images and 460 stereoscopic images. We are making the Waterloo IVC 3D Image Quality Database database available to the research community free of charge. If you use this database in your research, we kindly ask that you reference our paper listed below:
