Package boofcv.alg.filter.convolve

Class ConvolveImageNormalizedSparse

java.lang.Object

boofcv.alg.filter.convolve.ConvolveImageNormalizedSparse

public class ConvolveImageNormalizedSparse
extends Object

Performs a convolution around a single pixel only using two 1D kernels in the horizontal and vertical direction. Borders are checked and if on an image border the kernel is truncated and re-normalized. Only to be used with kernels that can be re-normalized

Method Details

convolve

public static float convolve(Kernel1D_F32 horizontal,
 Kernel1D_F32 vertical,
 GrayF32 input,
 int c_x,
 int c_y,
 float[] storage)

Convolves around the specified point in the horizontal and vertical direction. When at the border of the image the kernel is re-normalized.

Parameters:

horizontal - Kernel convolved across the point in the horizontal direction.

vertical - Kernel convolved across the point in the vertical direction.

input - Image being convolved.

c_x - The x-coordinate of the point being convolved.

c_y - The y-coordinate of the point being convolved.

storage - Temporary storage. Needs to be the same size as the kernels being convolved.

Returns:

Result of the convolution.

convolve

public static int convolve(Kernel1D_S32 horizontal,
 Kernel1D_S32 vertical,
 GrayU8 input,
 int c_x,
 int c_y,
 int[] storage)

Convolves around the specified point in the horizontal and vertical direction. When at the border of the image the kernel is re-normalized.

Parameters:

horizontal - Kernel convolved across the point in the horizontal direction.

vertical - Kernel convolved across the point in the vertical direction.

input - Image being convolved.

c_x - The x-coordinate of the point being convolved.

c_y - The y-coordinate of the point being convolved.

storage - Temporary storage. Needs to be the same size as the kernels being convolved.

Returns:

Result of the convolution.
