Since FFA responses decrease with decreasing contrast (experiment 3), this factor thus predicts smaller responses to faces at viewpoints rotated further from frontal.
At face value, this viewpoint suggests the absence of 'endogenous' depression, and that distress was fundamentally reactive.
Their heads take up most of their body, making the face the main viewpoint.
There's a scene at the end of Bruce Lee's 'Enter the Dragon' where Lee walks through a hall of mirrors, and there are frames where you see his face from several viewpoints simultaneously.
But this viewpoint faces serious problems.
Part of the brain's visual hierarchy appears to be specialized for recognizing faces from any viewpoint.
Clicking the XY-, XZ-, or YZ-plane buttons enables the jump to the viewpoint facing the selected plane at a right angle.
Coefficient based techniques estimate the face under all viewpoints given a single view, either by defining pose-invariant features known as "face lightfields" [44] or estimating the parameters of 3-D face models [45].
(b) Each set of samples with the same color represents face images under each viewpoint.
Green dots represent 30 subjects' face images under one viewpoint and one lighting condition.
