Speed, frequency, and orientation tuned 3-D Gabor filter banks and their design

Design of 3-D filters for image sequences is addressed. A family of filter banks which is capable of mimicking low level human motion perception i.e. being sensitive to low spatial frequencies moving fast and high spatial frequencies moving slowly, is proposed. The sensitivity is modelled quantitatively as existence of many filters with small band widths in a range of measurements. The speed, orientation, and spatial frequency tunings as well as the corresponding sensitivities are controllable in an explicit fashion. Implementation results are discussed
