skyview.process.imagefinder.Radius

public class Radius
extends Border

This class finds the best images to be used for sampling using a recursive rectangle algorithm. It looks for rectangles the boundaries of which can all be sampled from the same input image.

Method Detail

criterion

protected double criterion(int i,
                           int nx,
                           int ny,
                           double x,
                           double y)

Being close to the center is the goal.

Overrides:

criterion in class Border

Parameters:

i - The index of the image being considered

nx - The width of the candidate image

ny - The height of the caandiate image

x - The x-value of the requested point.

y - The y-value of the requested point.

Returns:

The inverse of 4 r^2. This is a little faster to computer so we use this rather than inverse of the radius.
