apply_zeroCrossing

public int[] apply_zeroCrossing(int[] src_1d,
                                int width,
                                int height,

                                float limit)

Applies the zero crossing detector to the input image

Parameters:

src_1d - The source image as a pixel array

width - width of the destination image in pixels

height - height of the destination image in pixels

kersize - The size of kernel to be applied

theta - The standard deviation of the gaussian smoothing

limiter - specifies whether to limit the zero crossing

limit - The limit applied to the zero crossings

Returns:

The output array with the zero crossing points
