Method Detail

• createARGBImage

  public static final BufferedImage createARGBImage(int[] pixels,
                                                    int width,
                                                    int height)

  Create a BufferedImage from an existing pixel array. Make sure that pixels.length == width * height.

  Parameters:

  pixels -

  width -

  height -

  Returns:

  BufferedImage

• sampleAverageScale

  protected static final double sampleAverageScale(CoordinateTransform ct,
                                                   int width,
                                                   int height,
                                                   double dx)

  Sample the average scaling of a given CoordinateTransform by transferring a set of point samples using the CoordinateTransform and then least-squares fitting a SimilarityModel2D to it.

  Parameters:

  ct -

  width - of the samples set

  height - of the samples set

  dx - spacing between samples

  Returns:

  average scale factor

• bestMipmapLevel

  protected static final int bestMipmapLevel(double scale)

• createScaleLevelTransform

  protected static final AffineModel2D createScaleLevelTransform(int scaleLevel)

  Create an affine transformation that compensates for both scale and pixel shift of a mipmap level that was generated by top-left pixel averaging.

  Parameters:

  scaleLevel -

  Returns:

• render

  public static final void render(Patch patch,
                                  int coefficientsWidth,
                                  int coefficientsHeight,
                                  ij.process.FloatProcessor targetImage,
                                  ij.process.FloatProcessor targetWeight,
                                  ij.process.ColorProcessor targetCoefficients,
                                  double x,
                                  double y,
                                  double scale)

  Renders a patch, mapping its intensities [min, max] → [0, 1]

  Parameters:

  patch - the patch to be rendered

  targetImage - target pixels, specifies the target box

  targetWeight - target weight pixels, depending on alpha

  x - target box offset in world coordinates

  y - target box offset in world coordinates

  scale - target scale
