Ecologically relevant canopy openness from hemispherical photographs

photographs with a full 180 degrees angle of view, but photographic equipment providing openness from the whole hemispherical photograph. Openness from 80 degrees - 120 affected by image quality and therefore more comparab...

Fisheye correction by CGA non-linear transformation

We provide a non‐linear image transformation by means of conformal geometric algebra (CGA) elements and operations. We show the correspondence to the fisheye correction algorithms; more precisely, we prove the proportionality of classical mo...

Validation of the fisheye camera method for spatial non-uniformity corrections in luminous flux measurements with integrating spheres

In this paper, the fisheye camera method is validated for spatial non-uniformity corrections in luminous flux measurements with integrating spheres. The method was tested in eight integrating spheres with six LED lamps, and the determined an...

Resolution of Maxwell's fisheye with an optimal active drain

We analyse the resolution of Maxwell's fisheye in terms of the efficiency with which a pulse emitted from one point (source) can be absorbed at another point (drain) that is slightly displaced from the position of the image of the source. Th...

Let's Get Dirty: GAN Based Data Augmentation for Camera Lens Soiling Detection in Autonomous Driving

Wide-angle fisheye cameras are commonly used in automated driving for parking and low-speed navigation tasks. Four of such cameras form a surround-view system that provides a complete and detailed view of the vehicle. These cameras are direc...
