The evolution of airborne mapping witnesses the introduction of hybrid lidar-camera systems to enhance data collection, i.e. to obtain simultaneously high-density point-cloud and texture. Yet, the common adjustment of both optical data streams is a nontriv ...

Patch-based matching is a technique meant to measure the disparity between pixels in a source and target image and is at the core of various methods in computer vision. When the subpixel disparity between the source and target images is required, the cost ...

Monocular depth cues, such as shading, are fundamental for resolving three-dimensional information, such as an object's shape. Animal colour patterns may potentially exploit this mechanism of depth perception, generating false illusions for functions such ...

The AVIRIS-4 is a state of the art imaging spectrometer developed by NASA-JPL for the consortium of Swiss universities ARES. Measurement campaigns using this instrument started in 2024. According to the agreement with NASA-JPL, all imagery produced by the ...

The Airborne Visible/Infrared Imaging Spectrometer-4 (AVIRIS-4) represents the next generation in the series of airborne imaging spectrometers built by NASA JPL. Commissioned by the Swiss ARES research consortium, AVIRIS-4 is geared towards delivering cutt ...
