Example 26 with Point

use of net.imglib2.Point in project imagej-ops by imagej.

the class PolygonFeatureTests method boundingBox.

@Test
public void boundingBox() {
    // ground truth verified with matlab
    final List<? extends RealLocalizable> received = GeomUtils.vertices(((Polygon2D) ops.run(DefaultBoundingBox.class, contour)));
    final RealPoint[] expected = new RealPoint[] { new RealPoint(1, 6), new RealPoint(1, 109), new RealPoint(78, 109), new RealPoint(78, 6) };
    assertEquals("Number of polygon points differs.", expected.length, received.size());
    for (int i = 0; i < expected.length; i++) {
        assertEquals("Polygon point " + i + " differs in x-coordinate.", expected[i].getDoublePosition(0), received.get(i).getDoublePosition(0), EPSILON);
        assertEquals("Polygon point " + i + " differs in y-coordinate.", expected[i].getDoublePosition(1), received.get(i).getDoublePosition(1), EPSILON);
    }
}

Example 27 with Point

use of net.imglib2.Point in project imagej-ops by imagej.
