TitleStereo Image Quality assessment Based on Perception and Statistical Model

Abstract: Stereoscopic image quality assessment (SIQA) plays a vital role in the application of 3D image and people’s QoE. This talk introducesthree objective SIQA models which is more consistent with the subjective opinions. Firstlyintroduces a full-reference (FR) SIQA metric by simulating binocular visual properties, which the objective quality scores are consistent with the subjective MOS scores.Secondly gives a reduce-reference (RR) SIQA using natural scene statistics (NSS) and structural degradation which combines NSS-based features with HVS-based features. It has the advantages of excellent performance, few reference information, low complexity and strong portability. Lastlyintroduces a blind SIQA model without the information of reference image using jointly statistics of binocular rivalry and orientation tuned responses.This metric achieves good performance and robustness, and also solves the problem of SIQA metric without the reference information of 3D image.

Title: Intelligent VisualEditing

Abstract: In this talk, I will briefly introduce some latest works in “VisualEditing” from my group. I will show how to generate fantastic special-effects for the typography. It is quite challenging due to the model diversities to illustrate varied text effects for different characters. To address this issue, our key idea is to exploit the analytics on the high regularity of the spatial distribution for text effects to guide the synthesis process.

Title: Reversible Data Hiding in JPEG Images, Dr. Zhaoxia Yin

Abstract:Reversible data hiding (RDH) is one special type of information hiding, by which the host signal as well as the embedded data can be both restored from the marked signal losslessly. Beside media annotation and integrity authentication, recently some scholars begin to apply RDH in many other fields innovatively, eg. Reversible Adversarial Example and Reversible Image Processing. More and more papers on increasingly wide-spread subjects in the field of RDH research have been published these days. In this report, the various RDH algorithms and researches will be mentioned and RDH into the most used image compressed domain, JPEG, will be addressed in detail. The history of JPEG RDH technical developments, the current state of the arts, and the possible future researches will be presented and discussed. It is expected that the JPEG RDH technology and its applications in the real word will continue to move ahead.

Title:Discovering Latent Discriminative Patterns for Multi-Mode Event Representation

Abstract: Representation of videos is essential since it conveys an understanding of video content and enables many higher level tasks to be tackled efficiently. However, it is challenging to propose a rational representation for complex event videos, as most video information is either noisy or redundant. We propose a compact event representation method that can concisely describe the inner modes of events. We deem that an optimal event representation scheme should reflect the long-term and high-level visual semantics (visual topics) of events, so different from previous frame-level video semantics representation methods and concept-based video representation methods, we investigate the problem from the perspective of segment-level video representations. We then present three appealing properties of segment-level visual semantics. Based on the observation, we propose different algorithms that rely on a novel deep-visual-word-based video encoding method to discover latent discriminative patterns of events. Finally, our multi-mode event representation is obtained by concatenating the discovered patterns as inner modes. We adopt our event representation for representative event parts mining, which can highlight the visual topics of events and remarkably prune the raw videos. We validate our event representation method based on complex event detection task.
