Second-order motion discrimination by feature-tracking
Second-order motion discrimination by feature-tracking is a scholarly work, published in 1999 in ''Vision Research''. The main subjects of the publication include tracking, computer science, motion, mathematics, motion perception, waveform, contrast, optics, spatial frequency, Stereo display, psychophysics, computer vision, physics, visual perception, color constancy, artificial intelligence, luminance, feature, distortion, and radar envelope. Observers report that the pattern moves in the direction of the contrast envelope when the jumps are repeated at intervals of more than 125 ms and in the direction of the luminance profile when they are repeated at longer intervals.
