Example 1 with DescribePointSurfPlanar

use of boofcv.alg.feature.describe.DescribePointSurfPlanar in project BoofCV by lessthanoptimal.

the class TestDetectDescribeSurfPlanar method basicTest.

@Test

    Planar<GrayF32> input = new Planar<>(GrayF32.class, width, height, 3);
    GImageMiscOps.addUniform(input, rand, 0, 200);

    DescribePointSurfPlanar<GrayF32> descMulti = new DescribePointSurfPlanar<>(desc, 3);
    FastHessianFeatureDetector<GrayF32> detector = FactoryInterestPointAlgs.fastHessian(null);
    OrientationIntegral<GrayF32> orientation = FactoryOrientationAlgs.sliding_ii(null, GrayF32.class);
    DetectDescribeSurfPlanar<GrayF32> alg = new DetectDescribeSurfPlanar<>(detector, orientation, descMulti);
    GrayF32 gray = ConvertImage.average(input, null);
    // see if it detects the same number of points
    detector.detect(gray);
    int expected = detector.getFoundPoints().size();
    alg.detect(gray, input);
    assertEquals(expected, alg.getNumberOfFeatures());
// could improve this unit test by checking scale and orientation
