Method Detail

stretch

public static <T extends ImageSingleBand> T stretch(T input,
                                    double gamma,
                                    double beta,
                                    double max,
                                    T 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.

public static <T extends ImageSingleBand> T brighten(T input,
                                     double beta,
                                     double max,
                                     T 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.
