new segmentation test

[alexlib]

@C73150N
please add a new test to https://github.com/OpenPTV/openptv/blob/master/py_bind/test/test_segmentation.py

we test now in

openptv/py_bind/test/test_segmentation.py

Line 36 in c249337

def test_two_targets(self):

the detection of two (1 pixel each) targets and check that there are 2 of them and then the first one is of the size 1 pixel. Actually it checks that it's 1 pixel in x, 1 pixel in y and 1 pixel in total.

Please add a new test in which an object is 3 x 2 pixels and we actually know which is x and which is y by the shape of that object, i.e.

        img = np.array([
            [0,   0,   0,   0, 0],
            [0, 255,   250,   250, 0],
            [0,   251,   253,   0, 0],
            [0,   0,   0, 251, 0],
            [0,   0,   0,   0, 0]
        ], dtype=np.uint8)

something like this, maybe there's a bug in this image. But we need to start by small steps

So, please:

1. fork this repo to your account
2. add the test
3. send us the pull request
