Mechanisms of Target Discrimination by the Echolocating Bat, Vampyrum Spectrum
… they were capable of discriminating between targets of differing shapes and sizes using echolocation alone. The study commenced with the demonstration that the bats could capture live mice, items similar to their normal prey, without recourse to visual or olfactory cues. The subsequent use of …

Investigating the contribution of parallel processing to visual search performance according to the Target Contrast Signal Theory
… pre-attentive stage that is based on saliency or target activation maps, Target Contrast Signal Theory (TCST) proposes that parallel processing in early vision involves evidence accumulation about how likely a given location is to contain the target in effort to reject items from further …

Unique and shared roles of the prefrontal and posterior parietal cortex in cognitive functions
… recordings. The average time of salient target discrimination in the dorsolateral prefrontal cortex appeared no later than the posterior parietal areas although the initial visual response latencies were earlier in the posterior parietal cortex than in the dorsolateral prefrontal cortex. …

Pose independent target recognition system using pulsed Ladar imagery
… these techniques have had limited success in target discrimination in part due to low-resolution data and limits in available computation power. We present a pose-independent Automatic Target Detection and Recognition System that uses data from an airborne 3D imaging Ladar sensor. The …

Variation in Visual Search Abilities and Performance
… sensory analysis, attentional allocation, target discrimination, and decision-making. Search abilities are malleable and vary in accordance with long-term experiences, direct practice, and contextual factors in the immediate environment; however, the mechanisms responsible for changes in …

Fusion of Full Waveform LiDAR and Passive Remote Sensing for Improved Land-Cover Classification
… utilized for classification because of the discrimination afforded by its rich spectral information and high resolution in both the spatial and spectral domains. On the other hand, LiDAR (Light Detection And Ranging) data has gained increasing interest for use in classification because it …

Advanced Methods for the Analysis of Radar Sounder Data Acquired at the Ice Sheets
… the automatic classification of ice subsurface targets in RS data. The core of the system is represented by the extraction of a set of features for target discrimination. The features are based on both the specific statistical properties of the RS signal and the spatial distribution of the ice …

Multi-wavelength, multi-beam, photonic based sensor for object discrimination and positioning
… of advanced laser scanning systems for discrimination in perimeter security, defence, agriculture, transportation, surveying and geosciences. Military forces, in particular, have already started employing laser scanning technologies for projectile guidance, surveillance, satellite and …
