    BoofTesting.assertEquals(expected, found, 1e-4);
    // change value

Example 2 with InterpolatePixel

use of boofcv.alg.interpolate.InterpolatePixel in project BoofCV by lessthanoptimal.

the class TestFDistort method setRefs.

/**
 * Makes sure that setRefs doesn't cause it to blow up
 */
@Test
public void setRefs() {
    ImageMiscOps.fillUniform(input, rand, 0, 200);
    FDistort alg = new FDistort();
    alg.setRefs(input, output).interp(InterpolationType.BILINEAR).scaleExt().apply();
    ImageDistort distorter = alg.distorter;
    InterpolatePixel interp = alg.interp;
    ;
    PixelTransform2_F32 outputToInput = alg.outputToInput;
    // a new image shouldn't cause new memory to be declared bad stuff to happen
    GrayU8 found = new GrayU8(width / 2, height / 2);
    GrayU8 expected = new GrayU8(width / 2, height / 2);
    alg.setRefs(input, found).scale().apply();
    assertTrue(distorter == alg.distorter);
