Examples with FloorInterpolatorFactory net.imglib2.interpolation.randomaccess.FloorInterpolatorFactory used on opensource projects

Example 1 with FloorInterpolatorFactory

use of net.imglib2.interpolation.randomaccess.FloorInterpolatorFactory in project imagej-ops by imagej.

the class RasterViewTest method defaultRasterTest.

@Test
public void defaultRasterTest() {
    Img<DoubleType> img = new ArrayImgFactory<DoubleType>().create(new int[] { 10, 10 }, new DoubleType());
    Random r = new Random();
    for (DoubleType d : img) {
        d.set(r.nextDouble());
    }
    RealRandomAccessible<DoubleType> realImg = Views.interpolate(img, new FloorInterpolatorFactory<DoubleType>());
    RandomAccessibleOnRealRandomAccessible<DoubleType> il2 = Views.raster(realImg);
    RandomAccessibleOnRealRandomAccessible<DoubleType> opr = ops.transform().rasterView(realImg);
    Cursor<DoubleType> il2C = Views.interval(il2, img).localizingCursor();
    RandomAccess<DoubleType> oprRA = Views.interval(opr, img).randomAccess();
    while (il2C.hasNext()) {
        il2C.next();
        oprRA.setPosition(il2C);
        assertEquals(il2C.get().get(), oprRA.get().get(), 1e-10);
    }
}

Example 2 with FloorInterpolatorFactory

use of net.imglib2.interpolation.randomaccess.FloorInterpolatorFactory in project imagej-ops by imagej.

the class InterpolateViewTest method defaultInterpolateTest.

@Test
public void defaultInterpolateTest() {
    Img<DoubleType> img = new ArrayImgFactory<DoubleType>().create(new int[] { 10, 10 }, new DoubleType());
    Random r = new Random();
    for (DoubleType d : img) {
        d.set(r.nextDouble());
    }
    RealRandomAccess<DoubleType> il2 = Views.interpolate(img, new FloorInterpolatorFactory<DoubleType>()).realRandomAccess();
