ABSTRACT:
An edge detection filter comprising an array of filter coefficients having an odd number of rows and columns, a first set of zero coefficients extending along a direction traversing the array through a center position to form a first and second side, a second set of positive coefficients extending away from the direction on the first side, and a third set of negative coefficients extending away from the direction on the second side.
