Examples of such cues include shading, texture, shadow, focus, perspective and groupings of vanishing points. These 'Shape-from-X' methods necessarily have to make assumptions about the scene structure to constrain the 3D solution — in general, a 2D projection has infinite 3D interpretations. ...
If there are ambiguities, the brain must make a decision favoring one or the other, perhaps favoring chromatic contrast because of its relative independence from shading. Other properties of an object, such as well-defined borders or texture, would be better determined by the achromatic system. ...
We recorded neural activity from 727 intracerebral contacts in 13 epileptic patients, while they detected near-threshold targets preceded by attentional cues. Clustering revealed three neural patterns: first, attention-enhanced conscious report accompanied sustained right-hemisphere fronto-temporal activity in...
varies over ten orders of magnitude (Fig.2), far from the equity expected from a strict size-numbers trade-off. Ecologists have long recognized a potential trade-off between producing few large seeds, each provisioned to attract dispersers and/or promote high seedling survival, versus many ...
for each season, and a lapse rate feedback is then calculated from each response using the radiative kernel method described above. Hence, the lapse rate feedbacks for the partial temperature response patterns sum to the total lapse rate feedback for the RCP8.5 forcing. The residual of the ...
Keywords: shape from shading; Mask R-CNN; segment highlight region; Lambert–Phong model 1. Introduction In the process of microelectronic high-speed dispensing, detecting the 3D shape of droplets online is a necessary precondition for studying the micro-jetting effect and realizing adaptive control...
The measurement was conducted from 10 a.m. to 2 p.m. During this period, the solar altitude is relatively high and the sun is near the center of the sky hemisphere, minimizing short-term indoor illuminance fluctuations, thereby ensuring the accuracy and reliability of the measurements. This ...
