Validating the integrity of pipes is an important task for safe natural gas production and many other operations (e.g. refineries, sewers, etc.). Indeed, there is a growing industry of actuated, actively driven mobile robots that are used to inspect pipes. Many rely on a remote operator to inspect data from a fisheye camera to perform manual inspection and provide no localization or mapping cap...

Person re-identification concerns the matching of pedestrians across disjoint camera views. Due to the changes of viewpoints, lighting conditions and camera features, images of the same person from different views always appear differently, and thus feature representations across disjoint camera views of the same person follow different distributions. In this work, we propose an effective, low ...

lighting plays a key role in night escapes of urban spaces, in a way that it can be effective in giving identity to them. by considering this importance and inexistence of a process for composing urban lighting strategy made this study to be conducted by the objective of providing process for compilation of context-oriented lighting strategy in urban spaces. reaching a suitable solution for lig...

In human-human communication we use verbal, vocal and non-verbal signals to communicate with others. Facial expressions are a form of nonverbal communication, recognizing them helps to improve the human-machine interaction. This paper proposes a system for poseand illumination-invariant recognition of facial expressions using near-infrared camera images and precise 3D shape registration. Precis...

The engineering of computer vision systems that meet application speci c computational and accuracy requirements is crucial to the deployment of real-life computer vision systems. This paper illustrates how past work on a systematic engineering methodology for vision systems performance characterization can be used to develop a real-time people detection and zooming system to meet given applica...

In this paper, we propose a system to achieve Augmented Reality (AR) on a smartphone. In this system, we assume a fixed RGB-D camera connected to a server is installed in the environment, and perform AR based on the 3D environment shape got by the RGB-D camera in real-time. On the smartphone side, it sends the image captured by its camera, and receives the output image processed to perform AR b...
