Design of an enhanced visual odometry by building and matching compressive panoramic landmarks online

Wei LU,Zhi-yu XIANG,Ji-lin LIU

Frontiers of Information Technology & Electronic Engineering 2015, Volume 16, Issue 2,   Pages 152-165 doi: 10.1631/FITEE.1400139

Abstract: In this paper, we propose an enhanced VO by introducing a panoramic camera into the traditional stereo-onlyBenefiting from the 360° field of view, the panoramic camera is responsible for three tasks: (1) detectingroad junctions and building a landmark library online; (2) correcting the robot’s position when thelandmarks are revisited with any orientation; (3) working as a panoramic compass when the stereo VO cannotTo use the large-sized panoramic images efficiently, the concept of compressed sensing is introduced

Memorial Building

Gu Mengchao

Strategic Study of CAE 2005, Volume 7, Issue 2,   Pages 15-19

Abstract:

In relation to the examples of memorial building in China and abroad, the article describes the historical evolution, type and characteristics of memorial building from the perspective of architectural philosophy. The article points out major problems in the design of memorial building in China. Mastering the intuition, experience, apriority and empathy of the architectural environment of memorial building is the key to the creation of memorial building.

Spontaneous versus posed smile recognition via region-specific texture descriptor and geometric facial dynamics Article

Ping-ping WU, Hong LIU, Xue-wu ZHANG, Yuan GAO

Frontiers of Information Technology & Electronic Engineering 2017, Volume 18, Issue 7,   Pages 955-967 doi: 10.1631/FITEE.1600041

Abstract: As a typical biometric cue with great diversities, smile is a fairly influential signal in social interaction, which reveals the emotional feeling and inner state of a person. Spontaneous and posed smiles initiated by different brain systems have differences in both morphology and dynamics. Distinguishing the two types of smiles remains challenging as discriminative subtle changes need to be captured, which are also uneasily observed by human eyes. Most previous related works about spontaneous versus posed smile recognition concentrate on extracting geometric features while appearance features are not fully used, leading to the loss of texture information. In this paper, we propose a region-specific texture descriptor to represent local pattern changes of different facial regions and compensate for limitations of geometric features. The temporal phase of each facial region is divided by calculating the intensity of the corresponding facial region rather than the intensity of only the mouth region. A mid-level fusion strategy of support vector machine is employed to combine the two feature types. Experimental results show that both our proposed appearance representation and its combination with geometry-based facial dynamics achieve favorable performances on four baseline databases: BBC, SPOS, MMI, and UvA-NEMO.
