Method Detail

mean

public static ImageUInt8 mean(ImageUInt8 input,
              ImageUInt8 output,
              int radius,
              ImageUInt8 storage)

Applies a mean box filter.

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 ImageUInt8 median(ImageUInt8 input,
                ImageUInt8 output,
                int radius)

Applies a median filter.

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 ImageUInt8 gaussian(ImageUInt8 input,
                  ImageUInt8 output,
                  double sigma,
                  int radius,
                  ImageUInt8 storage)

Applies Gaussian blur.

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.

mean

public static ImageFloat32 mean(ImageFloat32 input,
                ImageFloat32 output,
                int radius,

Applies a mean box filter.

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

Applies a median filter.

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
