Gaussian derivative kernels up to order four the two dimensional case.
R. A. Young. The squared responses of the cells at the dominant orientation at each position in the image is illustrated in Figure 11b. 2.2 Facilitation Units are interconnected by long range horizontal connections. In addition, there is a physiological motivation for using Gaussian filtered representations. Several researchers have used multi scale derivatives as a representation.
