During the competition, several factors that could decrease the effectiveness of the training result was quickly identified, such as the lack of distortion of provided training data, the high similarity between multiple images, and the extreme imbalance ...

We present MonoEye, a multimodal human motion capture system using a single RGB camera with an ultra-wide fisheye lens, mounted on the user's chest. Existing optical motion capture systems use multiple cameras, which are synchronized and require camera ...

Many vehicular accidents occur because of a blind spot. Previous studies of blind spot reveal that an algorithm becomes weak if the car is near, car detection is 5 to 10 meters only, and the detection rate is not high. A study on fisheye detection using ...

We present Touch180, a computer vision based solution for identifying fingers on a mobile touchscreen with a fisheye camera and deep learning algorithm. As a proof-of-concept research, this paper focused on robustness and high accuracy of finger ...

This paper proposes a client-server based mobile augmented reality system for illumination consistency between the virtual objects and the real world. The server system adopts a fisheye camera to capture real world illumination and transmits the light ...

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 ...

This study presents an approach for estimating the fisheye camera parameters using three vanishing points corresponding to three sets of mutually orthogonal parallel lines in one single image. The authors first derive three constraint equations on the ...

We present ViRi -- an intriguing system that enables a user to enjoy a frontal view experience even when the user is actually at a slanted viewing angle. ViRi tries to restore the front-view effect by enhancing the normal content rendering process with ...

In this paper, we present a cubic polynomial model for fisheye camera by using the lifting strategy, which point coordinates in low dimensional space is lifted to a vector in high dimensional space. In contrast to the lifting strategies reported, our ...

Mounting three fisheye cameras, on the sides and rear of a vehicle, can help a driver maneuver his/her vehicle in restricted environments by providing a top view that is generated from these three fisheye cameras. To generate the top view, the pose of ...

A fisheye camera calibration method is proposed by using two pairs of vanishing points from one single fisheye view in this paper. Aiming at a plane scene including two groups of parallel straight lines with different direction, one single fisheye image ...

This paper describes a prototype of a full-view spherical image sensor, gives a method for sensor calibration, and discusses display modalities of the captured full-view image for monitoring around a vehicle. To monitor the whole surrounding situation ...
