Analog Two-dimensional Network for Motion Detection Based on Lower Animal Vision
نویسندگان
چکیده
A two-dimensional network for motion detection constructed with simple analog circuits was proposed and designed based on the lower animal vision. In the frog visual system, output signals which correspond to the two-dimensional motion direction and velocity are generated by performing simple information processing at the tectum and thalamus. The measured results of the test chip fabricated with 1.2μm CMOS process showed that basic circuits utilized in the network can operate correctly. The results with the simulation program with integrated circuit emphasis (SPICE) showed that the network can generate currents which are proportional to the motion direction and the velocity of the object.

Analog Integrated Circuit for Detection of an Approaching Object with Simple-Shape Recognition Based on Lower Animal Vision
A network for the detection of an approaching object with simple-shape recognition is proposed based on lower animal vision. The locust can detect an approaching object through a simple process in the descending contralateral movement detector (DCMD) in the locust brain, by which the approach velocity and direction of the object is determined. The frog can recognize simple shapes through a simp...
