process

public void process(Image[] inputs,
                    Image output,
                    int[] selector,
                    Sampler samp,
                    DepthSampler dsamp)

Use as a postprocessor

Specified by:

process in class Processor

Parameters:

inputs - The array of input survey images.

output - The output user image. A null output may signal that an error has taken place. If this processor wishes to do something in response to the error, it may look at the ErrorMsg setting.

selector - An array giving the source image for each output pixel.

samp - The sampler object used to do spatial sampling of the input images.

dsamp - The sampler in the energy dimension (often null).

smooth

public static void smooth(Image img,
                          int boxWidth,
                          int boxHeight)

Smooth an image directly

smooth

public static void smooth(double[] data,
                          int imageWidth,
                          int imageHeight,
                          int imageDepth,
                          int boxWidth,
                          int boxHeight)

smooth

public void smooth()

Smooth the current image according to the prescribed size of the box. When going over the edges of the box we re-use the edge pixels.

updateHeader

public void updateHeader(nom.tam.fits.Header h)

Add information about the smoothing to the FITS header

Specified by:
