Package boofcv.alg.distort

Class PixelTransformCached_F32

java.lang.Object

boofcv.alg.distort.PixelTransformCached_F32

All Implemented Interfaces:

PixelTransform<Point2D_F32>

public class PixelTransformCached_F32
extends Object
implements PixelTransform<Point2D_F32>

Precomputes transformations for each pixel in the image. Doesn't check bounds and will give an incorrect result or crash if outside pixels are requested.

Method Details

getPixel

public Point2D_F32 getPixel(int x,
 int y)

isIgnoreNaN

public boolean isIgnoreNaN()

setIgnoreNaN

public void setIgnoreNaN(boolean ignoreNaN)

compute

public void compute(int x,
 int y,
 Point2D_F32 output)

Description copied from interface: PixelTransform

applies a transform to a pixel coordinate

Specified by:

compute in interface PixelTransform<Point2D_F32>

Parameters:

x - Pixel x-coordinate

y - Pixel y-coordinate

output - The transformed pixel

copyConcurrent

public PixelTransform<Point2D_F32> copyConcurrent()

Description copied from interface: PixelTransform

Creates a copy of this transform for use in concurrent application. What that means is that any variable which might be modified by a concurrent call to PixelTransform.compute(int, int, T) is not passed to the 'copied' output. Expensive to compute models might be passed in as a reference.

Specified by:

copyConcurrent in interface PixelTransform<Point2D_F32>
