....and parallel channels that are sensitive to both spatial frequency and orientation. Psychophysical evidence for the existence of such channels comes mainly from studies that use (i) summation at the threshold (Campbell and Robson, 1968; Graham and Nachmias, 1971) ii) selective adaptation (Blakemore and Campbell, 1969), and (iii) masking paradigms (Stromeyer and Julesz, 1972) Physiological studies found cells in V 1 (simple cells) that are selectively tuned to orientation as well as to spatial frequency and phase. It was suggested that the response profile of a simple cell could be approximated by 2D ....

....pairs were constructed to find a local oriented energy measure. Noise was then reduced by performing a soft threshold function [14] on the pyramid of multiscale coefficients. Each visual neuron can be characterized psychophysically by its receptive field (RF) Much psychophysical evidence [2], 7] shows that the RF cell is sentive to multiple, parallel bandpass neural images. Therefore, it is useful to decompose an image into a number of lowpass and bandpass subimages. Oriented linear or piecewise linear patterns are commom phenomena in nature and contain rich sources of image ....
