Density discrimination with occlusions in 3D clutter

RGB-D object recognition and localization with clutter and occlusions

Discrimination between Weather and Sea Clutter

The results of automatic discrimination between weather and sea clutter using S-band dual-polarization Doppler weather radar are presented. The data were collected with the NCAR SPOL radar located in the Pacific shoreline near Seattle, USA. The multiparameter dataset includes backscattered power P (or radar reflectivity Z), Doppler velocity V, spectrum width σv, differential reflectivity ZDR (p...

Occlusions in Face Recognition: a 3D Approach

The real challenge in face detection and recognition technologies is the ability to handle all those scenarios where subjects are non-cooperative and the acquisition phase is unconstrained. In the last few years a great deal of effort has been spent to improve the performances where cooperative subjects are acquired in controlled conditions. However, in those scenarios other biometrics, such as...

Adaptive Clutter Density in Multi-Hypothesis Tracking

In underwater surveillance active sonar is an important technological asset. Compared to passive sonar it features higher detection ranges and enables the detection of silent objects. As a drawback the interaction of sound waves with the seabed and the water surface causes false alarms, named clutter. False alarms usually appear randomly and variable in time and space. To distinguish false alar...

The effects of aging on contour discrimination in clutter

The present study examined the effect of aging on the detection and discrimination of contours embedded in a dense field of distractors. The minimum stimulus duration required to correctly discriminate (Experiment 1) and detect (Experiment 2) three types of "C" shaped contours was measured. Overall, older subjects required longer stimulus durations than younger subjects in all conditions. Compa...
