What optech's bathymetric LiDAR sees underwater

This article presents early results of the FUDOTERAM project using bathymetric LiDAR data acquired with the SHOALS-3000, the latest bathymetric LiDAR system from Optech. The survey area is in the coastal zone along the northern shore of Chaleurs Bay, in the western Gulf of St. Lawrence, Canada. The project aimed to apply the SHOALS3000 to geological mapping, sedimentary process monitoring and m...

What pattern the eye sees best

The visibility of gratings improves with increasing stimulus area. This effect is usually interpreted as being due to physiological summation within the extent of the largest spatial filter and due to probability summation between the outputs of linear, independent filters beyond that range. It is generally assumed that this improvement is isotropic to the patch configuration. In contrast, the ...

What the Robot Sees & Understands Facilitates Dialog

The particular applications that interest us include search and rescue robotics, security, elder/disabled care or assistance, or service robotics. In all of these application areas, visual perception and internal representations play a pivotal role in how humans and robots communicate. In general, visual perception plays an important role in communicating information amongst humans. It is typic...

Reading What the Mind Thinks From How the Eye Sees.

Human eyes convey a remarkable variety of complex social and emotional information. However, it is unknown which physical eye features convey mental states and how that came about. In the current experiments, we tested the hypothesis that the receiver's perception of mental states is grounded in expressive eye appearance that serves an optical function for the sender. Specifically, opposing fea...
