چکیده
A quick guide to the elementary motion detector- a model of how a simple neural circuit can detect visual motion, developed from work on insect vision but which seems also to be relevant to vertebrate visual systems.

Figure Tracking by Flies Is Supported by Parallel Visual Streams
Visual figures may be distinguished based on elementary motion or higher-order non-Fourier features, and flies track both. The canonical elementary motion detector, a compact computation for Fourier motion direction and amplitude, can also encode higher-order signals provided elaborate preprocessing. However, the way in which a fly tracks a moving figure containing both elementary and higher-or...

| We present two compact CMOS integrated circuits for computing the 2D local direction of motion of an image focused directly onto the chip. These circuits incorporate onboard photoreceptors and focal plane motion processing. With fully functional 14 13 and 12 13 implementations consuming less than 50 W per pixel, we conclude that practical pixel resolutions of at least 64 64 are easily achieva...

متن کاملA Model of Temporal Adaptation in Fly Motion Vision
A computational model is proposed to account for the adaptive properties of the fly motion system. The response properties of motion-sensitive neurons in the fly are modelled using an underdamped adaptive scheme to adjust the time constants of delay filters in an array of Reichardt detectors. It is shown that the increase in both temporal resolution and sensitivity to velocity change observed f...
