IEEE Workshop/Winter Conference on Applications of Computer Vision
Non-line-of-sight imaging (NLOS) is the process of estimating information about a scene that is hidden from the direct line of sight of the camera. NLOS imaging typically requires time-resolved detectors and a laser source for illumination, which are ...

This paper presents a design method for target enclosing of an underactuated autonomous surface vehicle to surround a maneuvering target with time-varying velocity, and both the target and the follower suffer from unknown ocean currents.

Wave-based non-line-of-sight imaging using fast f-k migration
ACM Transactions on Graphics, 2019Imaging objects outside a camera's direct line of sight has important applications in robotic vision, remote sensing, and many other domains. Time-of-flight-based non-line-of-sight (NLOS) imaging systems have recently demonstrated impressive results, but

Cooperative Active Aircraft Protection Guidance Using Line-of-Sight Approach
IEEE Transactions on Aerospace and Electronic Systems, 2021This article proposes sliding-mode-control-based guidance strategies for a team comprised of aircraft and a defending interceptor against an attacker. The proposed guidance strategies are based on the line-of-sight guidance concept.

The rock and coal, surrounding a coal mine tunnel, act as relatively low-loss dielectric media in the frequencies of range 200–4,000 MHz and dielectric constant of 5–10. Under these conditions a reasonable hypothesis is that the transmission takes the form of wave propagation, since the wavelength of ultra-high-frequency (UHF) waves are smaller than ...

A line-of-sight approach for non-line-of-sight imaging (Conference Presentation)
Computational Imaging IV, 2019Standard imaging systems, such as cameras, radars and lidars, are becoming a big part of our everyday life when it comes to detection, tracking and recognition of targets that are in the direct line-of-sight (LOS) of the imaging system. Challenges however start to arise when the objects are not in the system’s LOS, typically when an occluder is ...

Preferred Declination of the Line of Sight
Proceedings of the Human Factors Society Annual Meeting, 1985Thirty-two subjects participated in a study which measured the angle at which they preferred to look down at visual targets. Four different head positions, two visual tasks, and two target distances were used. The overall preferred mean angle in the midsagittal plane below the Frankfurt Plane was −34°. Head position and target distance had significant

Hokusai is among the best-known names in Japanese art, and it may be thought that only a deficiency of imagination could lead to more writing on him. Many other artists of his period have been entirely neglected in the contemporary literature. But in fact, there is still more to be said, and this short essay will attempt to introduce some ideas that ...

In the Line of Sight is a light installation that uses 100 computer-controlled tactical flashlights to project low-resolution video footage of suspicious human motion into the exhibition space. Each flashlight projects a light spot on the wall. All flashlights combined create a ten-by-ten matrix representation of the source footage, featured on a video
