Method Detail

mean

public static <T extends ImageSingleBand> T mean(T input,
                                 T output,
                                 int radius,
                                 T storage)

Applies a mean box filter.

Type Parameters:

T - Input image type.

Parameters:

input - Input image. Not modified.

output - (Optional) Storage for output image, Can be null. Modified.

radius - Radius of the box blur function.

storage - (Optional) Storage for intermediate results. Same size as input image. Can be null.

Returns:

Output blurred image.

median

public static <T extends ImageSingleBand> T median(T input,
                                   T output,
                                   int radius)

Applies a median filter.

Type Parameters:

T - Input image type.

Parameters:

input - Input image. Not modified.

output - (Optional) Storage for output image, Can be null. Modified.

radius - Radius of the median blur function.

Returns:

Output blurred image.

gaussian

public static <T extends ImageSingleBand> T gaussian(T input,
                                     T output,
                                     double sigma,
                                     int radius,
                                     T storage)

Applies Gaussian blur.

Type Parameters:

T - Input image type.

Parameters:

input - Input image. Not modified.

output - (Optional) Storage for output image, Can be null. Modified.

sigma - Gaussian distribution's sigma. If <= 0 then will be selected based on radius.

radius - Radius of the Gaussian blur function. If <= 0 then radius will be determined by sigma.

storage - (Optional) Storage for intermediate results. Same size as input image. Can be null.

Returns:

Output blurred image.
