                                MeanStarImageRadius mean_radius)

Deblends adjoining pixels into some sets of adjoining pixels based on the specified base step. After this process, this AdjoiningPixel is destroyed.

Parameters:

base_step - the step to deblend.

mean_radius - the mean radius of a star image.

getPeak

public Pixel getPeak()

Gets the pixel at the peak.

Returns:

the pixel at the peak.

getGravityCenter

public Position getGravityCenter()

Gets the gravity center.

Returns:

isAdjoining

private boolean isAdjoining(AdjoiningPixel ap)

Checks if the specified set of adjoining pixels is adjoining to this AdjoiningPixel.

Parameters:

ap - the target AdjoiningPixel to check.

Returns:

true if the specified set of adjoining pixels is adjoining to this.

extract

private void extract(int x,
                     int y)

Extracts and removes pixels around the specified position whose value is greater than the specified threshold. This method is invoked recurrsively.

Parameters:

x - the x position.

y - the y position.
