Method Detail

invert

public static ImageUInt8 invert(ImageUInt8 input,
                int max,
                ImageUInt8 output)

Inverts the image's intensity:
O_x,y = max - I_x,y

Parameters:

input - Input image. Not modified.

output - If not null, the output image. If null a new image is declared and returned. Modified.

Returns:

Output image.

brighten

public static ImageUInt8 brighten(ImageUInt8 input,
                  int beta,
                  int max,
                  ImageUInt8 output)

Brightens the image's intensity:
O_x,y = I_x,y + beta

The image's intensity is clamped at 0 and max;

Parameters:

input - Input image. Not modified.

beta - How much the image is brightened by.

output - If not null, the output image. If null a new image is declared and returned. Modified.

Returns:

Output image.

stretch

public static ImageUInt8 stretch(ImageUInt8 input,
                 double gamma,

                 int max,
                 ImageUInt8 output)

Stretches the image's intensity:
O_x,y = I_x,y&gamma + beta

The image's intensity is clamped at 0 and max;

Parameters:

input - Input image. Not modified.

output - If not null, the output image. If null a new image is declared and returned. Modified.

Returns:

Output image.

invert

public static ImageSInt16 invert(ImageSInt16 input,
                 int max,
